How much lux does the Sun emit? - Physics Stack Exchange I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly Now the
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

Equation of Earths Orbit around Sun (ellipse) These two distances help identify the location of the sun on the major axis of Earth's elliptical orbit Assume that the major axis of Earth is on the x-axis a Find an equation of the Earth's orbit about the sun b With the given information, estimate Earth's speed around the sun in milers per hour
How hot can metal get in sunlight? - Physics Stack Exchange I quite liked this one [archived] describing measurements on cars It shows that things left in the sun can get significantly hotter than the surrounding air (although there are some issues with the method used, the conclusions are mostly valid), One final note - how hot things are is not the same as how hot they seem to be
