Three main types of rocks found in space are Asteroids, Comets, and Meteors, believed to be remnants from the creation of the sun and planets. Asteroids are the largest space rocks, Comets are icy rocks with tails that can be millions of miles long when close to the Sun, and Meteors are meteoroids that burn up in Earth's atmosphere, with only about 500 meteorites reaching Earth's surface annually.
Insights
- Asteroids, Comets, and Meteors are three types of rocks found in space, believed to be remnants from the creation of the sun and planets, with Asteroids being the largest and classified as dwarf planets like Ceres.
- Comets, originating from the Kuiper Belt or Oort Cloud, have short-period comets like Halley's Comet orbiting the Sun every 76 years, displaying glowing comas and tails visible from Earth without a telescope, while Meteors, burning up in Earth's atmosphere, create meteor showers with only about 500 meteorites reaching the surface annually.
