Interesting Facts About Mercury:

Planet Order | Solar System Planets for Kids | Videos for Kids | Space Learning
  • Mercury is the fastest planet in the Solar System and completes an orbit around the Sun in just 88 Earth days going 29 miles per second.

  • From the ground, the Sun would be three times larger and seven times brighter than it is from the surface of Earth.

  • Mercury is only slightly larger than our moon. It is 2.6x smaller than Earth.

  • 2 NASA spacecraft explored Mercury, Mariner 10, and MESSENGER.

  • Natural Satellites : 0

  • Light speed from Sun: 5.97 min

Venus is the second planet from the Sun, between Mercury and the Earth. Venus has a very thick atmosphere that is full of greenhouse gas carbon dioxide that traps all the heat coming from the sun, making Venus the hottest planet in our solar system. Surface temperatures on Venus reach 475 degrees Celsius . The planet is made up of a rusty-colored surface that hosts thousands of volcanoes and extreme mountains.

Venus’s rotation is very interesting. The planet spins in the opposite direction of most other planets, and does so very slowly, making a day on Venus longer than a year!

Pluto: Once A Planet Now A Dwarf Planet

– Day: 6.4 Earth days

– Number of moons: 5

It is smaller than Earth’s moon its orbit is highly elliptical, falling inside Neptune’s orbit at some points and far beyond it at others and Pluto’s orbit doesn’t fall on the same plane as all the other planets instead, it orbits 17.1 degrees above or below.

It is smaller than Earth’s moon its orbit is highly elliptical, falling inside Neptune’s orbit at some points and far beyond it at others and Pluto’s orbit doesn’t fall on the same plane as all the other planets instead, it orbits 17.1 degrees above or below, taking 288 years to complete a single orbit 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.

What’s The Order Of The Planets In The Solar System

Over the past 60 years, humans have begun to explore our solar system in earnest. From the first launches in the late 1950s until today, we’ve sent probes, orbiters, landers and even rovers to every planet in our solar system. But can you name all eight of those planets in order? And can you put them in the correct order?

In case you’re a little rusty, we’ll break down some common ways to order the planets plus a few tricks to help you remember them going forward. Let’s start with the distance from the sun.

The most common way to order the planets is by their distance from the sun. Using this method, the planets are listed in the following order:

Contents

AU stands for astronomical units it’s the equivalent to the average distance from Earth to the sun . It’s a common way astronomers measure distances in the solar system that accounts for the large scale of these distances. To put it another way, Mercury, which is closest, is 35.98 million miles from the sun, while Neptune, the farthest, is 2.79 billion miles from the sun. Earth is 92.96 million miles from the sun.

Could There Be Life On Venus

Planets in Order from the Sun

Venus is very similar in size and structure to our planet, and is often called: “Earth Twin”. A better word for it would be “Toxic Twin”. There is simply no way that living organisms could survive on Venus. Besides the extreme heat, Venus is home to clouds full of sulfuric acid and an overall toxic atmosphere. If you thought this isn’t too bad, also know that the air pressure on Venus is 90 times more crushing than on Earth.

Despite this, scientists do not reject the possibility of life for tiny organisms, and theorize that microbes could exist high within the clouds, where the temperatures are cooler.

Nine Planets Become 12 With Controversial New Definition

The tally of planets in our solar system would jump instantly to a dozen under a highly controversial new definition proposed by the International Astronomical Union .

Eventually there would be hundreds as more round objects are found beyond Neptune.

The proposal, which sources tell SPACE.com is gaining broad support, tries to plug a big gap in astronomy textbooks, which have never had a definition for the word planet. It addresses discoveries of Pluto-sized worlds that have in recent years pitched astronomers into heated debates over terminology.

  • The asteroid Ceres, which is round, would be recast as a dwarf planet in the new scheme.
  • Pluto would remain a planet and its moon Charon would be reclassified as a planet. Both would be called plutons, however, to distinguish them from the eight classical planets.
  • A far-out Pluto-sized object known as 2003 UB313 would also be called a pluton.

That would make Caltech researcher Mike Brown, who found 2003 UB313, formally the discoverer of the 12th planet. But he thinks its a lousy idea.

Its flattering to be considered discoverer of the 12th planet, Brown said in a telephone interview. He applauded the committees efforts but said the overall proposal is a complete mess. By his count, the definition means there are already 53 known planets in our solar system with countless more to be discovered.

IAU members will vote on the proposal Thursday, Aug. 24. Its fate is far from clear.

Types Of Planets In The Solar System

The inner four planets closest to the sun Mercury, Venus, Earth and Mars are often called the “terrestrial planets” because their surfaces are rocky. Pluto also has a rocky, albeit frozen, surface but has never been grouped with the four terrestrials.

The four large outer worlds Jupiter, Saturn, Uranus and Neptune are sometimes called the Jovian or “Jupiter-like” planets because of their enormous size relative to the terrestrial planets. They’re also mostly made of gases like hydrogen, helium and ammonia rather than of rocky surfaces, although astronomers believe some or all of them may have solid cores.

If you were to order the planets by size from smallest to largest they would be Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter.

Jupiter and Saturn are sometimes called the gas giants, whereas the more distant Uranus and Neptune have been nicknamed the ice giants. This is because Uranus and Neptune have more atmospheric water and other ice-forming molecules, such as methane, hydrogen sulfide and phosphene, that crystallize into clouds in the planets’ frigid conditions, according to the Planetary Society . For perspective, methane crystallizes at minus 296 Fahrenheit , according to the U.S. National Library of Medicine .

How Did The Solar System Form

Solar system formation began about 4.5 billion years ago. Scientists have developed three models of how it happened.

Solar system formation began approximately 4.5 billion years ago, when gravity pulled a cloud of dust and gas together to form our solar system.

Scientists can’t directly study how our own solar system formed, but combining observations of young stellar systems in a range of wavelengths with computer simulations has led to models of what could have happened so many years ago.

How Many Planets Are There In Our Solar System

There are eight planets in our solar system, which is part of the Milky Way.

Pluto was once called the ninth planet in our solar system, but the International Astronomical Union made some category changes in 2006 and Pluto became a minor, or dwarf, planet.

The main reason for this decision is that Plutos wild-card orbit crosses the orbit of Neptune.

The idea of a ninth planet has persisted, and astronomers are now searching for Planet X, or Planet Nine, after mathematical evidence from 2016.

Planet Nine is thought to be five thousand times the mass of Pluto and 10 times the mass of Earth, and to orbit beyond Neptune.

Jupiter Is The Fifth Planet

Jupiter is the fifth planet in our solar system. It is located at an average distance of 484 million miles from our star. Jupiter is nicknamed the godfather of the solar system because its very strong gravitational influence attracts smaller objects such as asteroids towards the gas giant. Jupiter indirectly provides some protection to the 7 other planets, including the Earth, against asteroids.

    What Is The Position Of The Planets From The Sun

    The Sun is orbited by eight official planets which are held in place by the suns gravitational field. The planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are in the order of their distance from the Sun.

    However, this order of planets does not include the many dwarf planets. Ceres, the first dwarf planet, lies in the asteroid belt between Mars and Jupiter, whereas the remaining dwarf planets are in the outer Solar System and are Pluto, Eris, Sedna in order from the sun.

    Can You Walk On Saturns Rings

    Unfortunately, no. They look may look like solid structures but Saturns rings are actually made up of millions of debris floating in space. Some of these materials are as small as dust while some are as large as houses. Saturns gravity holds them together. But not only that, the planet has shepherd moons that keep these icy particles in place.

    Venus: Earths Twin In The Solar System

    Venus is the second planet from the sun and is the kind of hottest planet within the solar system. Its thick atmosphere is extremely toxic and composed of sulfuric acid clouds, the planet is an extreme example of the greenhouse effect.

    The average temperature on Venus surface is 900 F . At 92 bar, the pressure at the surface would crush and kill you. And oddly, Venus spins slowly from east to west, within the opposite direction of most of another planet.

    Venus is typically named Earthâs twin as theyre similar in size and radar images beneath its atmosphere reveal numerous mountains and volcanoes. But beyond that, the planets couldnt be more different.The Greeks believed Venus was two different objects â one within the morning sky and another within the evening. Because its often brighter than the other object within the sky, Venus has generated many UFO reports.

    Scientific Revolution And New Planets

    With the advent of the Scientific Revolution and the heliocentric model of Copernicus, Galileo and Kepler, use of the term planet changed from something that moved around the sky relative to the fixed star to a body that orbited the Sun, directly or indirectly . Thus the Earth was added to the roster of planets and the Sun was removed. The Copernican count of primary planets stood until 1781, when William Herschel discovered Uranus.

    When four satellites of Jupiter and five of Saturn were discovered in the 17th century, they were thought of as satellite planets or secondary planets orbiting the primary planets, though in the following decades they would come to be called simply satellites for short. Scientists generally considered planetary satellites to also be planets until about the 1920s, although this usage was not common among non-scientists.

    In the first decade of the 19th century, four new planets were discovered: Ceres , Pallas , , and Vesta . It soon became apparent that they were rather different from previously known planets: they shared the same general region of space, between Mars and Jupiter , with sometimes overlapping orbits, where only one planet had been expected, and they were much much smaller indeed, it was suspected that they might be shards of a larger planet that had broken up. Herschel called them asteroids because even in the largest telescopes they resembled stars, without a resolvable disk.

    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.
