How long until the sun gets burned down to the point where it cannot sustain life on earth anymore 1 watt is defined as 1 joule per second (j/s). 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
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? 6 at the sun's surface, sunlight is similar to black body radiation at the sun's surface temperature Thus, if you brought a surface next to the sun's surface, it would be able to heat up to that same temperature
And this temperature determines the entropy content of the sunlight
Now the sunlight leaves the sun and spreads out through space. 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
