This provides us with almost exact total solar 1 watt is defined as 1 joule per second (j/s). The sun's energy comes primarily from fusion of light elements in its core

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.
How has the distance between sun and earth been calculated
Also what is the size of 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?
1) the sun seems brighter (more dazzling) if there is more scattering in the atmosphere The sun would actually look very small to us in the sky if there were no atmosphere (it's the same angular size as the moon) and most of the brightness seen in the direction of the sun is from small deflection rayleigh scattering. 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
The moon's distance from the earth 3,480 km the sun's distance from the earth 149,000,000 km and diameter of 1,392,000 km 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
