How many total planets are there in the Solar System?

• A. 7
• B. 8
• C. 9
• D. 10

Answer: (B)

The correct answer is that there are a total of eight recognized planets in the Solar System. This includes Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Historically, there were nine planets when Pluto was classified as the ninth planet. However, in 2006, the International Astronomical Union redefined what constitutes a planet, leading to Pluto's reclassification as a "dwarf planet." This change reflects ongoing advancements in our understanding of celestial bodies. As a result, the current consensus is that the Solar System consists of eight planets. Understanding the classification criteria is essential in this context, as any references to earlier eras when Pluto was counted among the planets could lead to confusion. The current count is widely acknowledged and taught in educational settings, making it the accepted answer.
