Sun Suzie Complete Leaked Set #854

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 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'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. The sun will last, at its current brightness for 9 billion more years

How long until the sun gets burned down to the point where it cannot sustain life on earth anymore Those are completely different things As i asked before, separate threads, please. 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).

Here is the measured radiation from the sun it is fitted with a black body curve, at the top of the atmosphere (yellow) and even though it is evident that there are deviations from the theoretical black body, it is still a good approximation

Generally all bodies radiating are approximated with a black body spectrum If it fits well, that means that it also absorbs the same type of spectrum.
