SOLAR SYSTEM

Detailed explanation-1: -accretion-The process by which an object collects matter. For example, planet formation takes place as material orbiting a star gathers together through gravitational or electrostatic attraction, forming larger and larger bodies over time.

Detailed explanation-2: -The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

Detailed explanation-3: -What is accretion theory? Accretion theory explains the process of small clumps of dust gathering together to gradually form planetesimals. These planetesimals accumulate more materials and form protoplanets. These protoplanets build until they form planets within the solar system.

Detailed explanation-4: -Over time the planetesimals continued to collide and join together, attracted by gravity. These larger objects, about the size and mass of our Moon, are called protoplanets.

Detailed explanation-5: -A planetary system is a set of gravitationally bound non-stellar objects in or out of orbit around a star or star system.

Detailed explanation-6: -The planetesimal hypothesis suggests that planets form through the accretion of particles in the same orbit through collisions.
