... The 50 so-called exo-planets were discovered using a telescope that is found in South America. ... By looking at a star s wobble, astronomers can work out how many exo-planets are in orbit around it and how heavy they are. After studying all of the planets discovered with this telescope so far, astronomers have found that nearly half of stars that are similar to the Sun have at least one planet that is lighter than Saturn. ... But there are many, many more waiting to be found! ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...
