How many planets are in the solar system?

The solar system is known to have eight recognized planets. These planets, in order from the sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The distinction of eight planets is based on the formal definition set by the International Astronomical Union (IAU) in 2006, which reclassified Pluto as a "dwarf planet" rather than a full-fledged planet. This classification is grounded in specific criteria that a celestial body must meet to be considered a planet, which Pluto does not fulfill due to its inability to clear its orbital path of other debris. Thus, the count of eight planets is widely accepted in the scientific community and is consistent with current astronomical standards.
