Asteroids: Small Rocks with Big Potential Dangers

Asteroids are small, rocky bodies orbiting the sun, often referred to as minor planets. They originate from the debris of the solar system's formation, particularly influenced by Jupiter's gravitational pull. Asteroids vary in size and shape, with some potentially posing a threat to Earth. While most impacts are minor, a large asteroid could cause significant global damage. Scientists study asteroids to understand space matter and prepare for potential impacts.
