- What would happen if Jupiter collided with the Sun?
This question is inspired by a similar one asked on Quora Let's say a wizard magicked Jupiter into the Sun, with or without high velocity What happens? The Quora question has two completely oppo
- Is the distance between the Sun and the Earth increasing?
Besides the moon, the sun has a tidal component for the earths oceans, and when that crashes into continents the energy absorbed comes from the potential energy of the sun-earth system I am not sure how this compares to the distance loss due to the mass and energy radiation of the sun you mentioned

- Are planets actually moving in elliptical orbits around the Sun or do . . .

- Historically, how do we know that Earth moves around Sun? And it does . . .
Questions: -- Sun is something we see on daily basis, so it would not be strange if humankind got curious to know about it, and made theories,observations,maths to prove it How did Copernicus and others came up with the theory that earth moves around sun in elliptical orbit How did they prove it?
