How Many Moons Does Neptune Have
To date, 14 moons of Neptune have been discovered. The largest of these natural satellites is called Triton.
Triton is unique because it is the only large moon in the solar system with retrograde rotation. This means the direction of its spin is the opposite of its orbital direction around Neptune .
Astronomers suspect that Triton used to be part of the Kuiper Belta region of the solar system beyond Neptunebefore getting caught by Neptunes gravity.
Triton is the seventh-largest natural satellite in the solar system, after the Galilean moons of Jupiter, Saturns Titan, and our own Moon.

Human Exploration Of Neptune
Galileo came close to adding another spectacular discovery to his list of achievements when he observed Neptune with his telescope in December 1612 and January 1613. However, he marked it down as a star in his notebook.
In the decades following the discovery of Uranus in 1781, astronomers noticed the new planet did not precisely follow its expected path. Urbain Le Verrier and John Couch Adams independently predicted that these differences were caused by the gravitational pull of another, unseen planet.
Using Le Verriers calculations, Johann Gottfried Galle discovered Neptune on September 24, 1846.
In 1989 Voyager 2 became the firstand so far onlyspacecraft to visit the planet in a flyby.
Neptune The Other Blue Planet Of Our Solar System
Looking at the image of our solar system, one can spot the Sun in the centre and eight planets revolving around it. The planet revolving in the farthest orbit is Neptune, discovered 175 years ago on September 23-24, 1846.
Also referred to as the twin of Uranus because of its resemblance in terms of its bright blue colour, Neptune stands at a distance of 4.495 billion km from the Sun, has a surface area of 7.618 billion km² and has an apparent magnitude is around 7.67 to 8.00. Furthermore, being the farthest planet from the Sun, it has a huge orbit and an orbital period of 165 years.

Why Is The Discovery Of Neptune Still Considered A Controversy
Discovered in 1846, the three main astronomers behind its discovery were Urbain Le Verrier, Johann Gottfried Galle, and John Couch Adams. Their aim was to look for movements beyond Uranus and one night, they finally succeeded in finding a planet further away from it. They found its position only due to observed perturbations in the orbit of the planet Uranus. Furthermore, it is believed that it was first seen by Galileo, but he mentioned it as a star so the credit for its discovery can not be given to him.
The controversy behind the discovery of Neptune arose because some consider that its discovery was done by mathematical calculations while some think that it was randomly seen in the sky. This confusion has made it difficult for people to decide who gets the credit for the planets discovery.
The video mentioned below will show you the first real images of the blue planet that were released around the time of its discovery.

Important Questions With Answers
1. What is the colour of planet Neptune and why?
Neptunes colour is blue. This is because Neptunes methane atmosphere absorbs red and infrared light.
2. Why is there no life on Neptune?
The temperature, pressure and material on the planet Neptune are too unstable for all living things. For life to exist, the planet must have a permanent source of liquid water as well as a source of energy. There is no source of water and energy on Neptune. The temperature of Neptune is freezing, about 55 Kelvin. In no way can liquid water exist at this temperature. This is why there is no life on Neptune.
3. What cloud does Neptune have?
In our solar system, Neptune is located far away from the Sun, and it receives a tiny amount of thermal energy. Because of this, Neptune is an icy and very cold planet as compared to other planets. The white clouds of Neptune are formed of frozen methane. Such white clouds may be observed near Neptunes dark region, similar to Jupiters red eye, where storms occur. Storms on Neptune are much more intense than on the Earth, with wind speeds reaching 700 miles per hour. The remaining atmosphere of Neptune is made up of hydrogen, helium, and methane. Furthermore, the colour of the planets Neptune and Uranus is generated by methane in the atmosphere.
4. On Neptune, one day is equal to_______.

5. Do tornadoes exist on Neptune?
Nasa’s Hubble Finds A True Blue Planet
ABOUT THIS IMAGE:This illustration shows a hot-Jupiter-class planet orbiting its yellow-orange star, HD 189733. NASA’s Hubble Space Telescope measured the actual visible-light color of the planet, which is deep blue. This color is not due to the presence of oceans, but is caused by the effects of a 2,000-degree-Fahrenheit atmosphere where silicate particles melt to make “raindrops” of glass that scatter blue light more than red light.
The planet HD 189733b was discovered in 2005 and is only 2.9 million miles from its parent star. The planet is so close to its star that it is gravitationally “tidally locked” so that one side always faces the star and the other side is always dark. In 2007 NASA’s Spitzer Space Telescope made a thermal map that identified the presence of an early afternoon hotspot on the planet, as shown here. High-altitude clouds, laced with silicates, may blow from the day side to the night side at 4,500 miles per hour.
Because the planet is only 63 light-years from Earth, a visitor would see many of the same stars we see in our nighttime sky, though the constellation patterns would be different. Our Sun and the nearest star to our Sun, Alpha Centauri, appear as two faint stars near image center.

Which Is The Blue Planet In The Solar System
Neptune is the blue planet in the Solar System. The blue color comes from the methane gas in Neptunes atmosphere. Is there gas on Uranus? The planet Uranus does have gas. One of the most abundant is methane which makes the planet look blue. Why does planet Neptune look blue?
What makes the atmosphere of the planet Uranus blue?
Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue.
Why does Neptune look blue in the sky?
The planet Neptune looks blue because of the methane gas in the atmosphere. The methane absorbs the red spectrum from the dim sunlight that reaches Neptune and reflects the blue spectrum. This gives the impression to us that Neptune is a blue planet.
Which is the least dense planet in the Solar System?
It is the second least dense planet Saturn is the least dense of all. Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.
What Are The 9 Planets Of The Solar System
Almost all of us have looked up into the sky and wondered what is there. Well, there are lots of fascinating objects revolving out of space. Humans have left the earth in space ships to explore the solar system that surrounds it. Its known as the solar system since everything in it revolves around the Sun and solar means the Sun.
Eight known planets, the moon, as well as comets, asteroids and other space objects, revolve around the sun. The Sun is the largest object in the solar system. In fact, it accounts for 99% of the solar systems mass. Astronomers estimate that the solar system is more than 4.5 billion years old. Here is a rundown on the 9 planets of the solar system:

Eccentricity Of The Earth
The annual movement of revolution of the Earth, is moving the Earth to one degree per day in its orbit , with a lag of about 4 min between the mean solar day and the sidereal day. The Earth-Sun distance, which is 149.6 million km, on average, varies during the year. Earth passes each semester, alternately, at perihelion, i.e. it is at this time closer to the sun and at aphelion, i.e. it is at this moment the most away from the sun. The difference between these two distances is determined by the eccentricity. The orbital eccentricity is 0.017. Eccentricity measures the deviation of the Earth’s orbit with respect to a circular orbit. It goes from 0 for a circular orbit at 1 for a highly elliptical orbit. But the eccentricity of Earth’s orbit varies very slightly over time, between 0 and 0.06 with a period of 100,000 years. Calculating variations in temperature due to the eccentricity between the aphelion and perihelion are 4 ° Celsius.
How Long Would It Take To Get To Neptune
Neptune is the eighth planet from the sun and the final planet in the solar system, since scientists demoted Pluto from full planetary status to dwarf planet in 2006. Neptune is also the farthest planet in the solar system from Earth and orbits at a distance of between 2.7 billion miles and 2.9 billion miles from our planet, depending on where the two planets are in their orbits, Live Science’s sister site Space.com previously reported. The Voyager 2 probe took 12 years to reach Neptune, according to NASA’s Jet Propulsion Laboratory . However, the probe was traveling at an average speed of 42,000 mph much faster than humans have ever traveled.

Passage Dates At Aphelion And Perihelion
Dates of passage of the Earth at its aphelion and perihelion are not regular. For the Sun we speak of a Aphelion , the farthest point between the object and the Sun and a perihelion , the nearest point. But more generally speaking of apsis which designate the two extreme points of the orbit of a celestial object. The point at the minimum distance from the center of the orbit is called periapsis. The point at the maximum distance from the center of the orbit is called Apoapsis. The main axis of the ellipse that connects the periapsis and apoapsis an orbit is called apsis line. The names of these points, the closest and farthest from the central object, are specific of the central object name .
What Is Neptunes Opposition
A planets opposition occurs when Earth passes between it and the Sun. As a consequence of that geometry, Neptunes disk will appear to be 100% illuminated as seen from Earth. It will be 180º from the Sun and be closest to Earth in all of 2020.
The planet will therefore technically look at its brightest and best for all of 2020. It will rise at dusk in the east and set at dawn in the west.

The Various Moons Of Neptune
Neptune has 14 moons, each named after a minor sea deity or a nymph from Greek mythology. By far, the largest is Triton, whose discovery on October 10, 1846, was made possible by beer amateur astronomer William Lassell.
Neptunes only spherical moon is Triton. The planets remaining 13 moons are irregular in form. Triton is also the only big moon in the solar system to orbit its planet in the opposite direction of its planets rotation. This anomaly shows that Triton was originally a dwarf planet that Neptune grabbed rather than developing in place.

Why Is Neptune Blue
Neptune is blue because the atmosphere, made of helium and methane, absorbs red light while reflecting blue light. Methane only appears in trace amounts but it is to blame for the absorption of red light. Both Neptune and Uranus are made out of these materials. Uranus and Neptune are classified as ice giants. An ice giant is similar to a gas giant, the difference being that an ice giant contains more heavy elements in its interior than a gas giant does. Neptune is the furthest planet from the sun and is invisible to the naked eye. Interestingly, Neptune is the only planet in our solar system discovered through mathematics rather than observation. Astronomers had noticed irregularities in the orbit of Uranus that the gravitational pull of another planet could explain. When they looked at where this planet was predicted to be, they found Neptune.
How Long Does It Take To Get To Neptune
Every 176 years or so, the solar system aligns such that the outer planets become like stepping stones. A series of gravity assist maneuvers can swing a spacecraft from one planet to another and enable Jupiter, Saturn, Uranus, and Neptune to be visited within roughly a decade.
Voyager 2 made this Grand Tour in the late 1970s and 1980s. It took almost exactly 12 years to reach Neptune.

A Brief Overview Of Neptune
Neptune is the eighth planet from the Sun and the farthest known planet in the solar system. It lies on the inside edge of the Kuiper Belt, a large and rocky region of the solar system that contains the dwarf planets Pluto, Haumea, Makemake, and Eris.
Like Uranus, Neptune is an ice giant, with an atmosphere of hydrogen and helium, and an interior of slushy, rocky, icy material.
The blue tint of Neptune and Uranus comes from methane in their atmospheres. However, astronomers are unsure which chemical gives Neptune its particularly strong and striking shade of blue.
How To See Neptune
Get your self a pair of binoculars or a small telescope. You will need at minimum of a pair of binoculars, but they dont have to be largeany kind will do the trick, said Kerss. In binoculars it looks like a star, but its blueness does standout in a dark sky.
Its always tiny in telescopes, said Kerss. Always look at a star chart because its quite tricky to identifyeven Galileo mis-identified Neptune as a starbecause its never bright enough to spot with the unaided eye.

When Is Neptunes Opposition
You dont need to wait for one specific night to see Neptune. Although opposition is the only time when Neptunes disk is 100% lit by the Sun, it will be so far awayat 2.7 billion miles/4.3 billion kmthat it doesnt make much difference if you look at it away from opposition. Imagine the distance between the Earth and the Sun, and now consider that Neptune is 30 times that distance, said Tom Kerss, a British astronomy and science communicator who hosts the weekly Star Signs: Go Stargazing! podcast. The result is that Earths distance from Neptune doesnt change drastically in the course of a year, in percentage terms, so our view of Neptune doesnt change all that much.
