Neptune

17 Earth's could fit inside of Neptune.
A Neptune year is 60,190 Earth days.
A Neptunian day is 16 hours and 7 minutes long.
Its diameter is 50,538km.
It lies 4497 million km from the Sun.
Neptune spins at an inclination of 29 degrees off of its axis.
Johann Galle and Heinrich D'Arrest discovered Neptune in 1846 after two mathematians, U. J. J. Le Verrier and J. C. Adams predicted and calculated its position, because they noticed that the orbit of Uranus was peculiar, believing something to be pulling it in the opposite direction to the Sun.
The current number of Neptunian moons is estimated at 13.
Neptune's largest moon is Triton.Which is the only big moon in the solar system to orbit its parent planet in the opposite direction to its planet's rotation.
Triton is slowly getting closer to Neptune. Eventually it will get so close that it will get torn apart by Neptune's gravity and possibly form rings more spectacular than Saturn's rings.
The strongest winds in the solar system have been recorded on the planet Neptune, at speeds of up to 2,000km per hour.
Neptune has dark spots on it, similar to the Great Red Spot on Jupiter. These are areas of high atmospheric pressure, which force clouds of methane gas high up into the atmosphere appearing like cirrus (thin and wispy) clouds on Earth. However, these spots disappear and reappear on different parts of the planet, unlike Jupiters Great Red Spot.
Neptune sometimes orbits the Sun further away than Pluto, making it the most distant planet in the Solar System. It returned to its usual position (the second furthest planet away from the Sun) in december 1999.
Neptune has four faint rings. Some parts of these rings are brighter in areas than others and appear like arcs orbiting the planet, this may be because they are still forming.
Since its discovery in 1846, Neptune has still not completed a full orbit, as it takes 165 years for the planet to go around the Sun.
The coldest temperatures ever measured in the Solar System (-230 degrees celsius) have been recorded on Neptune's moon, Triton.
Pluto, a planet which has an orbit that sometimes crosses Neptune's may have been a moon of Neptune which escaped the planet's pull of gravity, but being prevented from escaping the Solar System by the gravitational pull of the Sun.

Nereid has the most eccentric orbit of the other moons in the solar system.Its distance from Neptune varies from around 1.35 million km to more than 9.62 million km.

Naiad is irregularly shaped.Orbitting Neptune every seven hours six minutes.

Other moons being Thalassa, Despina, Galatea, Larissa and Proteus.
