Neptune is known as the blue planet. It gets its colour because it is surrounded by methane gas. There are lots of interesting facts about Neptune.
You might think that where you live is windy, but Neptune is the windiest planet in our solar system, with winds of over 2,200 kph! For some reason, these winds always travel from east to west across the surface of the planet. It is also very cold on Neptune, with temperatures as low as 235 C.
When Voyager 2 passed Neptune, it observed four faint rings around the planet. It also discovered new moons. Neptune has eight moons — half as many as Jupiter. The largest of these moons is called Triton. This moon orbits in the opposite direction to all the other moons.
