These two distances help identify the location of the sun on the major axis of Earth's elliptical orbit. Assume that the major axis of Earth is on the x-axis. a. Find an equation of the Earth's orbit about the sun. b. With the given information, estimate Earth's speed around the sun in milers per hour.
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...

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). This provides us with almost exact total solar

3 The sun, moon, earth (and so on) all move around each other. The reason we say the earth moves around the sun is because the effects are more visible on a macro scale, and easier to predict with reasonable precision.
The Sun and Moon seem to have the same size because of this amazing coincidence: the moon is 400 times smaller than the Sun and 400 closer than the Sun. Checking 400 from this source:

Peter, effective temperature is basically the average temperature of a body orbiting the Sun. Sub-solar temperatures occur at the Sun's zenith for a body.
