Lets say a wizard magicked jupiter into the sun, with or without high velocity. An ideal periodic orbit would be an ellipse or a circle. This provides us with almost exact total solar The sun will last, at its current brightness for 9 billion more years. · 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). See comment by @user11153 … · do you want to know both how the earth-sun distance is measured and how the speed of light is measured? How long until the sun gets burned down to the point where it cannot sustain life on earth anymore? · 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 … So in approximately half a year the earth will have spun around its axis 182. 5 times. The quora question has two … I am more concer. Now take a look at. As i asked before, separate threads, please. · this question is inspired by a similar one asked on quora. · in an ideal two body system (say a sun and a planet), both bodies would move around their barycenter. · the earth takes 24 hours to spin around its own axis and 365 days to spin around the sun. Those are completely different things. 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. · 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. 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.
