Answer:Planet begins to form from a large cloud of gas and dust in space, called a "nebula". Over time, gravity pulls the particles in the cloud closer together, causing the cloud to slowly collapse and spin. As it spins, the material flattens into a disk called a "protoplanetary disk" with a new star forming at the center. Inside this disk, tiny dust particles stick together through static electricity and gentle collisions, forming larger clumps called "planetesimals" These clumps continue to collide and grow, eventually becoming "protoplanets". With enough time and material, a protoplanet gathers more mass and becomes a full planet, orbiting the star it formed around.
