How many planets are there in the solar system?

• A. 7
• B. 8
• C. 9
• D. 10

Answer: (B)

The number of planets in the solar system is currently established as eight. This count includes the planets recognized by the International Astronomical Union (IAU): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The classification of planets has undergone a change over time, particularly with the redefinition of what constitutes a planet, leading to the reclassification of Pluto as a "dwarf planet" in 2006. As a result, Pluto, along with other similar objects, is no longer counted as one of the primary planets of the solar system. The recognition of this current count of eight planets is widely accepted in the field of astronomy.
