Planet size refers to the physical dimensions of a planet, including its diameter, circumference, and volume. The size of a planet can vary greatly, with some planets being relatively small, like Mercury, and others being much larger, like Jupiter. The size of a planet can have significant implications for its composition, gravity, and ability to support life. Understanding the size of planets is important for studying their formation, evolution, and potential habitability. **

Pluto is classified as a dwarf planet by the International Astronomical Union (IAU) due to its size, orbit, and inability to clear its orbit of other debris. While it was previously considered the ninth planet in our solar system, its reclassification in 2006 sparked debate among astronomers and the public. Despite this controversy, Pluto remains an intriguing object in our solar system, with ongoing research and exploration shedding light on its unique characteristics. **

Pluto is no longer considered a planet because in 2006, the International Astronomical Union redefined the criteria for what constitutes a planet. According to the new definition, a celestial body must meet three criteria to be classified as a planet: it must orbit the sun, it must be spherical in shape, and it must have cleared its orbit of other debris. Pluto failed to meet the third criterion as it shares its orbit with other objects in the Kuiper Belt, leading to its reclassification as a dwarf planet. **

This is Earth, the third planet from the Sun and the only known planet to support life. It has a diverse range of ecosystems, including oceans, forests, deserts, and polar regions. Earth is also the only planet in the solar system known to have liquid water on its surface, which is essential for supporting life as we know it. **

Meteorites have the potential to cause significant damage to the Earth, but they are not typically considered "planet killers." While large meteorites can cause widespread destruction and even mass extinctions, the likelihood of a single meteorite causing the complete destruction of the planet is extremely low. However, the impact of a large meteorite could have catastrophic effects on the environment and life on Earth. Efforts to track and monitor near-Earth objects are important for mitigating the potential risks associated with meteorite impacts. **
