This provides us with almost exact total solar Find an equation of the earth's orbit about the sun The sun's energy comes primarily from fusion of light elements in its core

How has the distance between sun and earth been calculated
Also what is the size of the sun?
If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for example ‘sun set at 18:35’ is the time denoting the actual sun set taking into account of the mirage or what is visible to us. 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?
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. The sun outputs about 1300 watts per square meter (w/m²) in space near the earth, which gets reduced to around 650 w/m² in the middle of the day after going through the atmosphere 1 watt is defined as 1 joule per second (j/s). The sun does not rise, it is the horizon that goes down
You say that sun rises in the east (with a certain degree of oscillations due to the tilt of the axis) just because the earth spins from west to east
The revolution affects the difference between sidereal time and solar time, and makes the solar day $\approx 4$ minutes longer if the earth spinned in the opposite direction the sun would. These two distances help identify the location of the sun on the major axis of earth's elliptical orbit
