The Sun's satellites


Date: 2015-10-07; view: 364.


There are eight planets and a large number of smaller objects orbiting the Sun. (Exactly which bodies should be classified as planets and which as “smaller objects” has been the source of some controversy, but in the end it is really only a matter of definition. Pluto is no longer officially a planet but it is kept here for history's sake.)
