It is relatively easy to spot five of the planets in the Solar System. Mercury, Venus, Earth, Mars, Jupiter and Saturn are all visible with the naked eye.
Under ideal conditions Uranus is just barely visible to unaided viewers, but it is best to use binoculars or a telescope. You will definitely need magnification to see the eighth planet, Neptune.
Pluto lost its planet status in 2006 and is now considered to be a dwarf planet.
