Pluto is a planet.

The answer is false because Pluto is no longer considered a planet. In 2006, the International Astronomical Union redefined the definition of a planet, and Pluto did not meet the criteria. According to the new definition, a planet must orbit the Sun, be spherical in shape, and have cleared its orbit of other debris. While Pluto meets the first two criteria, it has not cleared its orbit and shares it with other objects in the Kuiper Belt. Thus, Pluto is now classified as a dwarf planet.
