Asteroids are leftovers from planet formation.

Asteroids are rocky remnants from the early formation of our solar system, primarily found in the asteroid belt between Mars and Jupiter. These celestial objects vary in size, with some as small as boulders and others as large as dwarf planets. Scientists study asteroids to learn more about the composition and history of our solar system. Some asteroids have even impacted Earth in the past, playing a significant role in shaping the evolution of our planet and life on it. Understanding asteroids is crucial for planetary defense and future space exploration endeavors.
