everyday life - Why do sunbeams diverge even though the sun is much ...
The Sun is very far away and the beams are pretty much parallel, but they're pointing towards you, and perspective makes them appear to converge towards the vanishing point - which in this case is the Sun's location in the sky.
astronomy - How big a coincidence is the Sun and Moon having almost ...
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
What is the simplest way to prove that Earth orbits 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?
What would happen if Jupiter collided with the Sun?
This question is inspired by a similar one asked on Quora. Let's say a wizard magicked Jupiter into the Sun, with or without high velocity. What happens? The Quora question has two completely oppo...
Is the distance between the Sun and the Earth increasing?
Besides the moon, the sun has a tidal component for the earths oceans, and when that crashes into continents the energy absorbed comes from the potential energy of the sun-earth system. I am not sure how this compares to the distance loss due to the mass and energy radiation of the sun you mentioned.
Why do we say that the Earth moves around the Sun?
3 The sun, moon, earth (and so on) all move around each other. The reason we say the earth moves around the sun is because the effects are more visible on a macro scale, and easier to predict with reasonable precision.
How long until the sun cannot sustain human life on earth?
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? Updated: I am more concer...
Sun light takes 1,000/30,000/100,000/170,000/1,000,000 years bouncing ...
When light (photon particle) is generated inside the Sun, it takes a long time to bounce around inside to later escape and travel outwards. Neutrinos escape immediately. The numbers for the years t...
Why doesn't sun go all the way to the horizon during sunset?
Everytime I see the pics of suset on beaches the sun appear to go all the way down to the surface of the sea (as shown in the picture) but when I see sunset in my region , the sun disappears well above the horizon. Why does that happen ? EDIT :- A better picture of the sunset.
Why is the Sun approximated as a black body at ~ 5800 K?
Approximating the sun as a black body effectively means that it's surface temperature is 5800K. And, indeed, if we look at the most dominant wavelength of the sun spectrum, the maximal intensity comes from green wavelength which corresponds to a black body emitting radiation at a temperature of 5800K.
