sun.....obviously
It does not. The Sun is the center of the solar system, and all of the planets and asteroids revolve around the Sun.
The Heliocentric Theory states that the Earth and planets revolve around a stationary Sun at the center of the solar system. The Sun is the center of the Solar System.
Geocentricism is the belief that the Earth is the center of the Universe and all other celestial objects revolve around it. (The Geocentric Theory)
The Sun.
Jupiter is not in the center of the universe, but rather at the center of its own orbit within our solar system. Its position is determined by the gravitational forces acting on it by the sun, which is at the center of our solar system.
The Heliocentric Theory is the theory that states the Sun is the center of the Solar System and all other celestial objects revolve around it. Supporting observations about the theory were by Galileo Galilei.
The main object in the solar system is the Sun. It has about 1000 times the mass of the largest planet, Jupiter; Jupiter, in turn, has more mass than all the other planets combined.
the sun's gravity
"geocentric"
The center of the orbit is between them in proportion to their masses. But the mass of the sun is so much larger compared to the mass of the planets that to a casual observer they do revolve around the center of the sun. Because planets don't orbit the exact center of stars, astronomers can see stars that "wobble" and can tell they have planets orbiting them. They will also get an idea of the period of those planets' revolutions around the star.
Our solar system has 8 regular planets and a number of dwarf planets.
The center of mass of the solar system is inside the sun, not too far from its geometric center.
