SOLAR SYSTEM

Detailed explanation-1: -The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object-such as a star or a planet.

Detailed explanation-2: -You actually exert a gravitational force on the Earth, but because your mass is many times smaller than the Earth’s mass, your pull is much less than the Earth’s. Gravity is measured as how fast objects accelerate towards each other. The average gravitational pull of the Earth is 9.8 meters per second squared (m/s2).

Detailed explanation-3: -Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force).

Detailed explanation-4: -Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall.
