Pluto is the correct answer because it was classified as a "dwarf planet" in 2006 by the International Astronomical Union (IAU). Before that, it was considered the ninth planet in our solar system. However, the IAU redefined the criteria for what qualifies as a planet, and Pluto did not meet all the requirements. It is now classified as a dwarf planet, along with other celestial bodies like Eris and Ceres.

The "lead" in a lead pencil is actually graphite. Graphite is a soft, black mineral that is commonly used in pencils due to its ability to leave a mark on paper.

Light travels through space at a speed of 186,000 miles per second. This is the speed of light in a vacuum, which is the fastest speed that anything can travel in the universe. Light can travel through space because it is made up of particles called photons, which do not require a medium like air or water to move through. This high speed allows light to cover vast distances in a short amount of time, making it possible for us to see objects in space that are millions or even billions of light-years away.
