The Edge Of The Solar System
Past the Kuiper Belt is the very edge of the solar system, the heliosphere, a vast, teardrop-shaped region of space containing electrically charged particles given off by the sun. Many astronomers think that the limit of the heliosphere, known as the heliopause, is about 9 billion miles from the sun.
The Oort Cloud lies well past the Kuiper Belt, considered to be located between 2,000 and 5,000 astronomical units from the sun. The outer edge of the Oort Cloud may reach as far as 10,000 up to 100,000 AU from the sun. One AU is equal to approximately 93,000,000 miles . The Oort Cloud is home to billions, or even trillions of objects, according to NASA Science .
Where Is Earth In Our Galaxy
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group a galaxy called the Milky Way.
How big is the solar system?
Sedna is three times farther away from Earth than Pluto, making it the most distant observable object known in the solar system. It is 143.73 billion km from the Sun, thus giving the Solar System a diameter of 287.46 billion km.

Comparison With Extrasolar Systems
Compared to many extrasolar systems, the Solar System stands out in lacking planets interior to the orbit of Mercury. The known Solar System also lacks super-Earths, planets between one and ten times as massive as the Earth, although the hypothetical Planet Nine, if it does exist, could be a super-Earth beyond the Solar System as we understand it today. Uncommonly, it has only small rocky planets and large gas giants elsewhere planets of intermediate size are typicalboth rocky and gasso there is no “gap” as seen between the size of Earth and of Neptune . As many of these super-Earths are closer to their respective stars than Mercury is to the sun, a hypothesis has arisen that all planetary systems start with many close-in planets, and that typically a sequence of their collisions causes consolidation of mass into few larger planets, but in case of the Solar System the collisions caused their destruction and ejection.
The orbits of Solar System planets are nearly circular. Compared to other systems, they have smaller orbital eccentricity. Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined.
What Do The Planets In Our Solar System Look Like
Long answer. Our solar system is composed of planets, comets and asteroids along with other space dust and debris that orbit the star we call the sun. Formed more than 4 1 2 billion years ago, our solar system is one of various others like it in the Universe. It is situated on one of the four arms of the Milky Way, a.k.a the Orion arm.

Faq: Which Spacecraft Are Headed To Interstellar Space
Five spacecraft have achieved enough velocity to eventually travel beyond the boundaries of our solar system. Two of them reached the unexplored space between the stars after several decades in space.
- Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. Both spacecraft are still in communication with Earth. Both spacecraft launched in 1977.
- NASA’s New Horizons spacecraft is currently exploring an icy region beyond Neptune called the Kuiper Belt. It eventually will leave our solar system.
- Pioneer 10 and Pioneer 11 also will ultimately travel silently among the stars. The spacecraft used up their power supplies decades ago.
Solar System Map Of Current Planetary Positions
Both apps show a solar system map – a “plan view” of the planets laid out in the plane of the ecliptic .
Dwarf planet positions are also shown – but it should be realised that these objects often rise far above and below the plane of the ecliptic. This is because their orbital planes are tilted with respect to the ecliptic – by more than 40 degrees in some cases. So be aware that just because the app may occasionally show a planet and a dwarf planet to be very close to each other in the plan view, they may, in fact, be separated by a large perpendicular distance.

A Faraway Solar System Is An Uncanny Reflection Of Our Own
Astronomers have captured a strangely comforting scene 300 light-years from Earth.
This article was updated on August 3, 2020, at 11:55 am.
Astronomers have a saying about how difficult it is to see a distant planet outside of our own solar system: Its like spotting a firefly next to a lighthouse.
Stars are so luminous that they block our view of planets that might be orbiting nearby, so astronomers have to work around them. They use special instruments on telescopes to block the light coming from these celestial beacons. With the glare gone, they can detect something else: heat radiating off of planets. In the resulting observations, the worlds are easier to spotglowing orbs in the darkness, like fireflies hovering in the heat of a summer night.
This is how astronomers captured two planets around a star that resides about 300 light-years away from Earth. The portrait, released yesterday, is rare. Astronomers have directly taken images of individual exoplanets before. And they have previously captured cosmic family portraits: planets together with stars brighter and heavier than our sun. But this is the first time anyone has captured two exoplanets around a sunlike star.

Explanation:
#color# Our solar system is composed of planets, comets and asteroids along with other space dust and debris that orbit the star we call the sun. Formed more than #4 1/2# billion years ago, our solar system is one of various others like it in the Universe. It is situated on one of the four arms of the Milky Way, a.k.a the Orion arm.
All of the objects that comprise the solar system originated from huge cloud of gases and dust called as nebula. This cloud began to spin slowly and then faster, with the matter in the center spinning and collapsing in on itself. This became the sun.
Other parts of matter spun off from this cloud and became the planets. Some planets became large enough to attract large amounts of gases. These became the giant planets that include Jupiter, Saturn, Uranus and Neptune. These bodies rotated around the Sun in orbits, thus becoming the solar system.
The inner four planets are much smaller than the outer four. These planets have dense, rocky cores, and only Earth and Mars have moons orbiting them.
The outer planets have gaseous surfaces, mostly helium and hydrogen and ice, which implies one cannot be able to land on them. They have many moons in orbit around them, as their gravitational fields are stronger than the inner planets.

What Does The Edge Of The Solar System Look Like
It’s weirder than you may have imagined.
Earth is the sixth planet from the edge of the solar system, meaning we’re none too near this cold and inhospitable frontier. But we’ve sent out various spacecraft over the years, so do we have any idea what the edge of the solar system looks like?
The answer is yes, but it’s a work in progress. One of the latest developments, a 3D map of the solar system’s edge that took 13 years to create, revealed a few more secrets about this mysterious boundary, called the outer heliosphere.
The outer heliosphere marks the region of space where the solar wind, or the stream of charged particles emitted from the sun, is “deflected and draped back” by the interstellar radiation that permeates the empty space beyond the solar system, said Dan Reisenfeld, a space science researcher at Los Alamos National Laboratory in New Mexico and head of the team that conducted the research on the 3D map. In other words, solar wind and interstellar particles meet and form a boundary at the far reaches of the solar system.

Neptune: A Giant Stormy Blue Planet
– Day: 19 Earth hours
– Number of moons: 14
Neptune is approximately the same size as Uranus and is known for its supersonic strong winds. The planet is more than 30 times as far from the sun as Earth.
Neptune was the first planet predicted to exist by using math, rather than being visually detected. Irregularities in the orbit of Uranus led French astronomer Alexis Bouvard to suggest some other planet might be exerting a gravitational tug. German astronomer Johann Galle used calculations to help find Neptune in a telescope. Neptune is about 17 times as massive as Earth and has a rocky core.

Composition Of The Solar System
Located at the centre of the solar system and influencing the motion of all the other bodies through its gravitational force is the Sun, which in itself contains more than 99 percent of the mass of the system. The planets, in order of their distance outward from the Sun, are Mercury, Venus, Earth, , Jupiter, Saturn, Uranus, and Neptune. Four planetsJupiter through Neptunehave ring systems, and all but Mercury and Venus have one or more moons. Pluto had been officially listed among the planets since it was discovered in 1930 orbiting beyond Neptune, but in 1992 an icy object was discovered still farther from the Sun than Pluto. Many other such discoveries followed, including an object named Eris that appears to be at least as large as Pluto. It became apparent that Pluto was simply one of the larger members of this new group of objects, collectively known as the Kuiper belt. Accordingly, in August 2006 the International Astronomical Union , the organization charged by the scientific community with classifying astronomical objects, voted to revoke Plutos planetary status and place it under a new classification called dwarf planet. For a discussion of that action and of the definition of planet approved by the IAU, seeplanet.
This Is What The Solar System Really Looks Like
At first glance, it looks like something from an alien autopsy. A strange organ cut from a xenomorphs thorax, under the flickering lights of an operating room in a top secret government facility, with venous tendrils dangling down to the floor, dripping viscous slime.
But no, its just our Solar System.
This strangely fascinating shape is actually a graphic representation of what our Solar System looks like, or rather the magnetic bubble that surrounds our Solar System. Its a representation of the heliosphere, a massive bubble carved into space by the Suns constant outflow.
Theyre calling it the deflated croissant model.
The problem with measuring the heliosphere accurately is that were inside it. Its edge is over 16 billion km away. Its only thanks to the pair of Voyager spacecraft that we have any data at all from outside the heliosphere. Voyager 1 left the helisphere behind and entered interstellar space in August 2012, and Voyager 2 did the same in November 2019.
But the data from those interactions is complex. It has to be fed into computer models to come up with any sensible predictions about the nature and shape of the heliosphere. NASA and the NSF have funded an effort to make sense of it, called the SHIELD Drive Science Center, at Boston University.
But this new research is showing us a different heliosphere. More recent evidence, the authors point out, shows that the heliosphere contains two jet-like structures.

From 1979 until early 1999, Pluto had been the eighth planet from the sun. Then, on Feb. 11, 1999, it crossed Neptune’s path and once again became the solar system’s most distant planet until it was redefined as a dwarf planet. It’s a cold, rocky world with a tenuous atmosphere.
Scientists thought it might be nothing more than a hunk of rock on the outskirts of the solar system. But when NASA’s New Horizons mission performed history’s first flyby of the Pluto system on July 14, 2015, it transformed scientists’ view of Pluto.
Pluto is a very active ice world that’s covered in glaciers, mountains of ice water, icy dunes and possibly even cryovolcanoes that erupt icy lava made of water, methane or ammonia.

Searching For More Planets Circling White Dwarfs
Astronomers have found evidence for planets orbiting white dwarfs before, but none of those detections are quite like this new one. In 2019, an international team of astronomers spotted a gassy debris ring around a white dwarf and surmised that a small, dense planetary remnant may be embedded in the debrisa destroyed world that may resemble Earths inevitable fate. Several other debris disks have also been identified, thought to be the shredded remains of unfortunate planets and asteroids.
Last year, another team using NASAs exoplanet-hunting TESS instrument identified a candidate planeta giant worldorbiting a white dwarf in a mere 34 hours. That planet is so close to its host star, it would have definitely been engulfed during the red giant phase, Becker says. Which means it had to migrate into its location after the star became a white dwarf.
And over the last two decades, scientists have seen smears of chemical elements on white dwarf stars facesthe crumbs of chewed up, rocky worlds.
All of these observations, in addition to the newly discovered system, suggest that some planets can survive their host stars evolutionary transformationsat least for a time. But the processes that determine whether a planet survives or meets its doom are still fuzzy.

Solar System Formation And Discovery
Approximately 4.5 billion years ago a dark cloud of gas and dust began to collapse. As it shrank, the cloud flattened into a swirling disk known as a solar nebula, according to NASA Science .
The heat and pressure eventually became so high that hydrogen atoms began to combine to form helium. The nuclear reactions released vast amounts of energy and our sun was formed.
The sun accumulated about 99% of the available matter and the remaining material further from the sun formed smaller clumps inside the spinning disk. Some of these clumps gained enough mass that their gravity shaped them into spheres, becoming planets, dwarf planets and moons. Other leftover pieces became asteroids, comets and smaller moons that make up our solar system.

For millennia, astronomers have followed points of light that seemed to move among the stars. The ancient Greeks named them planets, meaning “wanderers.” Mercury, Venus, Mars, Jupiter and Saturn were known in antiquity, and the invention of the telescope added the Asteroid Belt, Uranus, Neptune, Pluto and many of these worlds’ moons. The dawn of the space age saw dozens of probes launched to explore our system, an adventure that continues today.
There have been five human-made objects so far, Voyager 1, Voyager 2, New Horizons, Pioneer 10 and Pioneer 11, that have crossed the threshold into interstellar space.
