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. So in approximately half a year the earth will have spun around its axis 182. 5 times. An ideal periodic orbit would be an ellipse or a circle. Lets say a wizard magicked jupiter into the sun, with or without high velocity. The quora question has two … · 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 … This provides us with almost exact total solar I want to know how much lux the sun emits on a bright day - i dont mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly. · this question is inspired by a similar one asked on quora. · the earth takes 24 hours to spin around its own axis and 365 days to spin around the sun. · its 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). · the sun is 1000 times more massive than jupiter, so the sun-jupiter barycenter is about 1/1000th of the way from the suns center of mass to jupiters center of mass. I am more concer. · in an ideal two body system (say a sun and a planet), both bodies would move around their barycenter. · do you want to know both how the earth-sun distance is measured and how the speed of light is measured? Those are completely different things. 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? See comment by … As i asked before, separate threads, please.
