Apr 27, 2018 · However, the Sun will accrete $\sim 10^{42}\ \mathrm{kg\ m^2\ s^{-1}}$ of angular momentum, which is comparable to its current angular momentum. The accretion of Jupiter in this way is therefore sufficient to increase the angular momentum of the Sun by a significant amount. In the long term this will have a drastic effect on the magnetic ...

Apr 27, 2015 · Another way of calculating the earth - sun distance is to look at the centrifugal and the gravitational force. This solution assumes that one already knows the mass of the sun, but thats a different problem ;-).

Feb 15, 2017 · The Sun has actually set/risen and we see it due to the way light is bent across the atmosphere. Apparently due to coincidence of the size and distance of the sun, its exactly the same size - so if we see 50% of the sun, the sun is 50% below the horizon. So, I understand all this, so here is my question :

Jan 8, 2024 · At the sun's surface, sunlight is similar to black body radiation at the sun's surface temperature. Thus, if you brought a surface next to the sun's surface, it would be able to heat up to that same temperature. And this temperature determines the entropy content of the sunlight. Now the sunlight leaves the sun and spreads out through space.

Dec 21, 2015 · Here is the measured radiation from the sun . It is fitted with a black body curve, at the top of the atmosphere (yellow) and even though it is evident that there are deviations from the theoretical black body, it is still a good approximation.

The continuous spectrum of the visible photosphere of the Sun is attributable to the radiative equilibrium of the $\mathrm{H}^{-}$ ion. This has been recognised for at least 80 years ( Wildt 1939 ). This ion forms by the attachment of a free electron (with a continuous spectrum of energies) to a hydrogen atom, emitting a continuous spectrum of ...

Jul 22, 2017 · The moon or the sun on the other hand do not appear noticeably smaller, because their real distance does not change much when they move to the horizon. But the brain would expect them to be smaller, much as the clouds, or a plane, and hence perceives them as larger than they 'should be'.

Inside the sun’s radius, however, is a different story. As it currently stands, the curvature of spacetime increases as one approaches the sun’s radius and then, after passing the boundary, decreases until levelling out in the center of mass of the sun.

Mar 31, 2013 · In principle the tidal forces of the Sun will eventually slow the Earth's rotation so it always shows the same face to the Sun. However I suspect this would be such a slow process that the Sun will have formed a red giant and swallowed the Earth before it's complete. However it is not unknown for the axis of rotation of planets to change.
