Which gravitational differences we would feel if the sun disappeared?
I would like to start by stating that I'm not a physicist, I'm purely a curious individual.
I've been speculating about the differences the loss of the sun's gravitational field would have on us and ...

Weight dependency on the location on Earth relative to Sun
In this post a theoretical physicist says that one will weigh less at the point on the Earth closest to the Sun due to the Sun's gravity, which makes sense to me. But he also says that one will weigh ...

The role of the Sun in spring and neap tides
I am trying to understand how the Sun affects tides on the Earth's oceans and seas.
It is quite clear that when the Moon is in the first and in the third quarter, the Sun's and the Moon's ...

In the difference between the sun and moon's tidal effects on earth, is density or distance a larger factor?
This question is inspired by the (now looking at it, improper use of, my bad) comments section here in Physics SE. I'm not sure I could explain better than our short discussion does below:
No, the ...

Are there any effect of Sun to the tide? [duplicate]
The Earth is rotating for the Sun's gravitational field. Like a free falling object Earth should feel zero gravity to the Sun. So why there are effect of Sun to the tide?

If the Earth would change into a ball of water, how wil its form develop, considering only the Sun's and Moon's influence? [duplicate]
Let's fantasize that the Earth changes in a non-rotating ball of water. And let's assume the only gravitational influences on it are those of the Sun and Moon.
What will happen to the form of the ...

If gravity can be disrupted by larger forces, why does the moon orbit the Earth instead of the Sun? [duplicate]
I read an thread on this site about how a larger gravitational pull can overpower a smaller gravitational pull. I took this to mind, and I started wondering why the moon orbits the Earth instead of ...

Gravitational effect of larger solar system to Earth orbit
Let's say our solar system enters to gravitational area of a larger solar system. Does Earth's orbit of sun get affected from this case?

Gravity Sun Earth Moon [duplicate]
The gravitational pull the Sun has on the Moon is roughly two times greater than the pull the Earth has on the Moon. If this is the case, why does the Sun's gravity not pull the Moon away from the ...
