The planet furthest from the Sun is Neptune. It is a brother of Uranus and therefore also an Ice giant with a temperature of -220 C.
Neptune has 9 rings and probably 16 moons. We don’t know exactly yet because we can’t see the smallest moons from Earth. The largest is Triton, which is the coldest celestial body in our solar system (-237 C). Neptune was only discovered because Uranus deviated a bit from its orbit and from that the position of Neptune could be calculated.
Storms rage at the equator of Neptune at speeds of up to 2400 km / h. Sometimes dark spots appear on Neptune, which are then hurricanes
