As we have seen in discussing the individual terrestrial planets, there are huge differences in atmospheric mass, composition, & surface temperature despite a modest range of distances (only a factor of 2) from the Sun and similar masses, at least for Venus & Earth.. There is a 10,000:1 range in the mass of the atmospheres of the three planets. Most of the several hundred thousand asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt. Later, civilizations like the Greeks and the Chinese invented a system of fortunetelling involving the patterns of the stars. the last name of the first man to take a step on the moon.

It has one natural satellite, the Moon, which is the only large satellite of a terrestrial planet in the Solar System. the most important gas in Earth's atmosphere. But planets around red dwarfs are also likely to be “tidally locked”—always presenting one side to the star, in the same way our moon shows only one face to the Earth.
