Planets are created through a process called accretion in the early stages of a solar system’s formation. Here’s a simplified overview:1. Formation of a Star: A star forms from a cloud of gas and dust in space, known as a molecular cloud.2. Protoplanetary Disk: Around the young star, a rotating disk of gas and dust forms. This is called the protoplanetary disk.3. Accretion: Small particles in the disk collide and stick together, forming larger bodies called planetesimals.4. Formation of Protoplanets: These planetesimals collide and merge to form protoplanets, which are larger bodies that will eventually become planets.5. Clearing the Disk: As the protoplanets grow, their gravity attracts more material, and they clear their orbits of remaining debris.6. Final Planets: Over millions of years, the protoplanets become fully-formed planets, orbiting the star.This process happens over billions of years and results in the formation of planets like Earth.
