- How is distance between sun and earth calculated?
How has the distance between sun and earth been calculated? Also what is the size of the sun?
- What is the simplest way to prove that Earth orbits the Sun?
Assume you're talking to someone ignorant of the basic facts of astronomy How would you prove to them that Earth orbits the Sun? Similarly, how would you prove to them that the Moon orbits Earth?

- Black and white matters. But why and how? - Physics Stack Exchange
So a metal door in the sun will transfer the heat of the visible spectrum to the interior if painted black, will reflect it back and keep the interior cooler if painted white It is a good reason for painting roofs and walls white in hot countries A white car is also better in hot countries for this reason
- What is the average distance between objects in our asteroid belt?
Asteroids are not distributed uniformly in the asteroid belt, but could be approximated to be evenly spaced in a region from 2 2 AU (1 AU is 93 million miles, or the average distance between Earth and the Sun) to 3 2 AU from the Sun and extending 0 5 AU above and below the ecliptic (the plane of Earth's orbit, which is a convenient reference
- sun - How far has Earth moved from its birth orbit? - Physics Stack . . .
So how far has earth moved towards or away from the sun in these 4 5 billion years? Now perfect balance between the centrifugal force of orbital rotation and sun's gravity is impossible so the earth's orbit should either be slowly decaying inwards or expanding outwards due to difference in magnitude of those opposing forces
- sun - Why is sunlight spectrum continuous? - Physics Stack Exchange
The sun's spectrum is very complex, and indeed there are a lot of "lines"—both light and dark (emission and absorption)—amidst a sea of what looks to be continuous frequencies
- Can Jupiter be ignited? - Physics Stack Exchange
Our solar system itself contains two candidate "Earths" One is Jupiter's moon Europa and another is Saturn's moon Titan Both of them have the problem of having at low temperature as Sun's heat ca
