It doesn't gravity is a myth made up by Issac Newton to become famous, we are actually held on the earth by tiny magnet in our feet.
it uses its force to make the planets orbit the sun.
it helps us by the sun and moon
All solar orbits (of planets, comets, asteroids, etc.) are the work of gravity. Without gravity, each of these objects would sail off in a straight line, and there would be no solar system. Actually, when you think about it, gravity is what holds the sun together. So without it, there would be no sun, and without a sun, there certainly couldn't be a solar system. And also oh by the way, gravity is what holds each planet and asteroid together.
because the gravity of the earth and heat of the sun ..
The solar system works by all planets lined behind each other and rotating in a circle around the sun, earth turns but since we have gravity we don't fall and the sun shows on the side the earth faces it and the moon on the other,so gravity holds all planets,sun, moon.stars,and everything in space, PLanets:mercury venus earth mars Jupiter Saturn uranus neptune, and by the way Pluto is not a planet it is a star which was discovered by scientist, and they discover a new planet.:)
Gravity is the force that pulls objects towards each other, such as the sun and planets in our solar system. Inertia is the tendency of objects to resist changes in their motion. Gravity keeps planets in orbit around the sun by balancing the planets' inertia with the force of gravity pulling them towards the sun.
Yes, stars do exert the majority of the physical force (gravity) which dictates the gross structure of a solar system; gravity being consequential to mass - which is an intrinsic property of matter, in this case, the matter in the star. To a lesser extent, planets, gas, dust, and other objects contribute to gravitational forces at work in a solar system. The general definition of a solar system is the region in which the central star's gravitational force is dominant.
The work done by gravity on the two-block system is equal to the force of gravity multiplied by the distance the blocks move in the direction of gravity.
Mercury is the smallest planet in our solar system excluding Pluto.
Galileo had a theory, it was that the earth was NOT in the centre of the solar system like everyone thought, he made the first telescope and proved everyone wrong by looking into space and seeing that the sun was in the centre of the solar system, not the earth, doing this he also invented the telescope.
He was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe.
The magnetic core of the earth pulls on the mass of the pencil.
