Astronomy: Our Solar System

There are much interesting objects and bodies in our solar system to observe. For instance, in 1930 Pluto was discovered as the ninth planet. Only in 1978 it was discovered Pluto has a moon. And in 2006 the International Astronomical Union ruled that Pluto no longer is considered to be a planet (because many other similar size rocks were discovered and aren't classified as planets either). >> The Sun >> Mercury >> Venus >> Earth >> Mars >> Jupiter >> Saturn >> Uranus >> Neptune >> Pluto (since 2006 no longer a planet)
