I'll assume you mean the lit side of the Moon (this wasn't clear from the original question, but I've edited it). Suppose there's a crescent Moon visible in the sky during the day. Plot a straight line between the tips of the crescent, then plot a perpendicular straight line across its center across the sky. Intuitively, that line should pass through the ...

Yes - the earth and sun do have tidal forces like the moon and earth. There are two main reasons this is happening. The sun is always losing mass due to nuclear reactions, the sun is always converting a tiny amount of its mass into energy. This means the pull on the earth is weakened. The tidal forces that happen between us on the moon happen between the ...

Well, I wasn't sure if tidal forces between Earch and Sun were strong enough to have any effect on the matter. Truth to be told, the article barrycarter linked clarifies that tidal forces have neglible meaning in comparison to the effect of Sun's nuclear fusion mass loss. That's correct. Some more details on this. Tidal "tugging" is a two ...

You may find this article by Phil Plait or this one on EarthSky.org interesting.Basically, a new hypothesis proposes that, after the impact that created the moon, it got tidally locked to the Earth in only a few (~100) days. Because the Earth was still hot (2,500°C) from the residual heat of impact, it cooked the near side but let the far side cool more ...

The near side and far side have very different topography. Compared to the near side, the far side is far more rugged and has far fewer maria. The near side in places has very thin crust (the maria). Other than these surface features, the biggest indicator of a disparity in crustal thickness is the two kilometer offset between the Moon's center of figure ...

Saturn and Jupiter have many moons for quite a few reasons, one of the main ones being that they have an absolutely immense gravitational pull. During the early stages of the formation of our solar system, there would of been many planet-like objects floating around which our gas giants would have attracted. Furthermore, these planets are so far out in the ...
