WebAfter this little physics class, we present the 12 types of satellites and their characteristics. Do not miss it. 1. Natural satellites. As we have said before, a satellite can be natural or artificial. The former are celestial bodies that orbit the planet, that is, they do not correspond to human constructions launched with a specific objective. WebClose to the Earth at an altitude of 100 km, a satellite needs to be moving at 8 kilometres per second (28,000 km/h) to stay in orbit. At higher altitudes, satellites do not need to be travelling as fast. Television communication satellites are at a higher altitude of 36,000 km and only need to travel at 3 km/s (11,000 km/h).
