Pluto is not considered a planet.

Pluto is not considered a planet.

• A. False
• B. Not stated
• C. Depends on context
• D. True

Answer: (D)

Planet classification relies on a formal definition that goes beyond appearance or popularity. According to the current standard, a body must orbit the Sun, be nearly round in shape, and have cleared its orbital neighborhood of other debris. Pluto meets the first two criteria but has not cleared its orbit, sharing the region with many other objects in the Kuiper Belt. Because of that, it’s classified as a dwarf planet rather than a full planet. So the statement that Pluto is not considered a planet is true under the official definition, even though some people still call it a planet in casual use.
