the Solar System planets

The Solar System planets orbiting our Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and dwarf planet Pluto.

Pluto lost its designation as a planet when it was reclassified as a dwarf planet.

When did Pluto lose planet status? In August 2006, Pluto was excluded from ‘planet’ category and renamed as a dwarf planet. The debate continues about whether it is the ninth planet or not but at the time of this writing, it remains classified as a dwarf planet.
