This provides us with almost exact total solarThu, 30 Apr 2026 10:13:00 GMThttps://physics.stackexchange.com/questions/154951/why-do-sunbeams-diverge-even-though-the-sun-is-much-more-than-a-few-kilometers-aThe 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.Thu, 30 Apr 2026 01:02:00 GMThttps://physics.stackexchange.com/questions/167463/how-much-lux-does-the-sun-emitI 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 theWed, 29 Apr 2026 22:03:00 GMThttps://physics.stackexchange.com/questions/10933/why-do-we-say-that-the-earth-moves-around-the-sun3 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.Thu, 30 Apr 2026 14:02:00 GMThttps://physics.stackexchange.com/questions/402383/what-would-happen-if-jupiter-collided-with-the-sunThis 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...Thu, 30 Apr 2026 01:02:00 GMThttps://physics.stackexchange.com/questions/39098/how-long-until-the-sun-cannot-sustain-human-life-on-earthThe 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?

Those are completely different things. As I asked before, separate threads, please.Wed, 29 Apr 2026 14:03:00 GMThttps://math.stackexchange.com/questions/4433526/how-to-get-3d-coordinates-xyz-of-the-sun-given-azimuth-and-altitude-elevation0 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). Main question: I need to calculate the 3D coordinates (XYZ) from the sun Azimuth and altitude/elevation Look at the image.Thu, 30 Apr 2026 01:02:00 GMThttps://physics.stackexchange.com/questions/467613/why-is-the-sun-approximated-as-a-black-body-at-5800-kApproximating 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.Tue, 21 Apr 2026 02:31:00 GMT
