If this is to do with gravity are there any variables which mean we might one day see more than we have before? 16 why do i sometimes see a horizontal half moon, instead of the more usual vertical one I keep getting answers for crescent moons, but this is a half moon with its curve closer to the horizon, like a bowl of cereal I would like to know why it only appears sometimes that way. If the moon is actually close to the earth, and simply moving above it, then we should be able to see different sides of it A person standing on the equator, directly above the moon, would only see the underside.
10 our moon and saturn's moon, titan, have this feature Because of this we only observe one side (hemispere) of our moon What is the newtonian or astrophysics that would explain this It seems that it would be some kind of equilibrium that is arrived at over time, but i don't understand it. This explain why we only see one face of the sun and moon throughout the day Hypothetically, a flat sun which faces down could also work in this model
1 the far side of the moon feels less pull from the earth than the near side The moon travels along the path of its center of mass This means the mass further feels less gravitational pull from the earth plus it is pulled outwards by centrifugal force (because it is going too fast for an orbit at its distance). The dark side is the far side, not the half that isn't lit up by the sun It's the half that faces away from earth We can't see the dark side of the moon for the same reason that we can't see the back of a person's head when they're facing us.
The sun is visible but the moon is not visible at new moon, as it is lost in the glare of the sun Note that while the positions of the sun and moon are correct, their sizes are not. The moon was made by smashing out a chunk of the earth, and so somehow preserved some orbital rotation from the earth 2 The gravitational drag from the earth to the moon is lowest when the moon is in 'sync' to only show one face to the earth
