The sun will last, at its current brightness for 9 billion more years. As i asked before, separate. 1) the sun seems brighter (more dazzling) if there is more scattering in the atmosphere.
Those are completely different things. The sun does not rise, it is the horizon that goes down. 0 i want to create an augmented reality (ar) application to show the sun's position where i need the 3d (xyz) coordinates to plot in augmented reality (ar).
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. 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. 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). Long story short, my brother made a joke about how stupid it is to celebrate the earth making one trip around the sun:
So i got curious and was wondering:. 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. How long until the sun gets burned down to the point where it cannot sustain life on earth anymore?
