evidence that support the heliocentric theory?

Answer 1

The gravitational theory supports this. When two bodies revolve each other their masses must satisfy the equation (M1*M2)/D^2.

In the solar system if we consider sun & a planet , the mass & diameter of sun is such a huge value so that the Centre of Combined Mass is within the Sun & hence sun is almost sationary when compared to any planet.

But the general thinking of Moon goes round earth is questionable to the extent that which revolves round which as both are revolving & since combined CG is out side both.

Answer 2

Practically all observations of planet and sun positions are evidence that support the heliocentric theory, if they are accurate enough.

Kepler (1571 - 1630) managed to describe the positions of the planets and the sun, using simple laws that that used the Sun at one focus of the orbits.

That's really all that "heliocentric theory" means == the equations of orbit motion for the planets are simplest when the position of the Sun is used as the center of the orbits, including the orbit of the Earth. It's not necessary to show that the planets "really" orbit around the sun (whatever that means); we just have to show that the Sun-centered equations are simpler, for example, than Earth-centered equations.

Answer 3

Goes back to before Western time was recorded in China and in other civilisations in South America. In Italy, someone I believe in the 15th century took a metal ball, attached it to a rope or metal wire and hung it from inside a tower. It was high enough that as the earth moved the ball would not rotate but travel along a circle that was painted on the floor in relationship to the movement of the earth.

Answer 4

path of the planets through space is most simply described with sun at approximate center. (of course, the whole system is part of a group of local stars, which is all headed towards a big glut of other stars)

Answer 5

We have 'flown' spacecraft around the sun, what more proof do you need?
