All About Neptune

All About Neptune


First things first, the moon orbits the planets and the planets orbit the Sun.

The gravity of the Sun keeps all the planets in their orbits, just like the planets gravity keeps the moons in their orbits.

An orbit is a journey/path that an object takes in space. For example, stars, planets and moons.

Gravity is the invisible pulling force that works in space. Earth’s gravity is what keeps us on the ground.

Neptune and Uranus look quite similar and are made of the same materials.

They are known as distant twins, however looks hide many differences.

Like Earth, Neptune rotates on a slight tilt as it travels in space.

Neptune is the windiest planet in our solar system.

Neptune is the eight and farthest-known planet from the Sun.

From the Sun the eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Jupiter, Saturn, Uranus and Neptune are know as the Outer Planets.

A Neptune year is the same as 165 Earth Years.

A Neptune day is 16 hours and 7 minutes.

Neptune has 14 moons. They are called, Triton, Thalassa, Naiad, Nereid, Proteus, Hippocamp, Galatea, Despina, Neso, Halimede, Laomedeia, Psamathe, Larissa and Sao.

The largest of Neptune’s moons is Triton

Neptune is named after the Roman God of the Sea.

Astronomer, Johann Galle saw Neptune for the first time through a telescope in 1846. He named it after the Roman God of the Sea, due to it’s bright blue color.

Similar to Earth, Neptune has clouds and storm systems that revolve around the planets atmosphere.

Neptune has only been visited once, by the same Voyager 2 that took the only photos of Uranus, Saturn and Jupiter.

The Voyager 2 was launched in 1977, to study the giant planets in our Solar System. It passed Neptune in 1989, and is now passing through the outer reaches of the Solar System, transmitting scientific data back to NASA.

Neptune is 30 times further away from the Sun than Earth.

Neptune, Uranus, Jupiter and Saturn are know as the four Gas Giants.

Neptune’s atmosphere is made up of hydrogen, methane and helium.

Neptune has at least five rings which are very faint. They are made up of very tiny dust like particles.

Neptune is the fourth-largest planet by diameter.

At first Neptune was called Le Verrier, named after the man who discovered it, Urbain Le Verrier, a French mathematician. Both Le Verrier and John Adams in England had realized that a hidden planet was pulling on Uranus, causing it to speed up and slow down.

Neptune has an average temperature of -353°F or -214°C.

Neptune is 4.5 billion kilometers away from the Sun, which means it is very cold.

Neptune is the coldest planet in the solar system

As Neptune is so far away from the Sun, it has a high proportion of ice present, due to the extreme cold conditions.

Neptune is 2700 million miles or 4345  million kilometres away from Earth.
