There are eight recognized planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. This classification does not include dwarf planets such as Pluto, which was reclassified by the International Astronomical Union in 2006. Each planet has distinct characteristics, orbits, and compositions, varying from rocky terrestrial bodies like Earth and Mars to gas giants like Jupiter and Saturn. The solar system also contains moons, asteroids, and comets, contributing to its complexity. The study of these planets enhances our understanding of planetary formation, evolution, and the potential for life beyond Earth.
