Neptune is a giant planet, 4 times larger than Earth. It emits a lot of internal heat, but it is inferior to Jupiter and Saturn in this indicator.
There are 13 known moons of Neptune, the largest of which (Triton) is geologically active and has geysers of liquid nitrogen on its surface. It is the only satellite that moves in the opposite direction.
An interesting fact is that the planet is accompanied by the so-called Neptunian Trojans, which are asteroid-type bodies.
Among all the planets in the solar system, Neptune has the strongest winds. According to some estimates, their speeds can reach 2100 km / h
Neptune has rings, but its ring system is much less significant compared to Saturn’s rings we are used to.
