The quora question has two. The question is a bit unrealistic with its circumstances but lets assume there is a bucket of ice cooled down to about absolute zero and is about 1000 km away (all around the sun) from sun. It's consensus that the very similar apparent sizes of the moon and the sun as seen from earth is a coincidence (as already answered in this site).
Those are completely different things.
As i asked before, separate threads, please. Assume you're talking to someone ignorant of the basic facts of astronomy. How would you prove to them that earth orbits the sun? How long until the sun gets burned down to the point where it cannot sustain life on earth anymore?
But that doesn't mean that the temperature of the sun has to be terribly high. This question is inspired by a similar one asked on quora. This provides us with almost exact total solar My understanding is that the sun is basically a sphere of hydrogen with a helium core, and that the hydrogen is undergoing nuclear fusion to produce helium.
The sun will last, at its current brightness for 9 billion more years.
