from east to west against the background stars maybe?
The sun does not move along a celestial orbit. Planets move along a celestial orbit around the sun. The planet, the sun, the milkyway galaxy and the rest of the galaxies are circling the universe. Q: When did man discover this?
The stars in the Ptolemaic model of the universe move on or are attached to a celestial sphere.
Astronomers know that there isn't really a "celestial sphere", a globe of crystal in which the stars are embedded. But it is often convenient to talk of a "sphere" around the Earth, in which all the stars and planets move. And sometimes it makes the math a whole lot easier. Navigators do all their calculations AS IF all the stars were stuck to a crystal sphere, and the Moon and planets wandered around inside it.
counter-clockwise
gravity
Celestial objects such as the sun appear to rise in the east and set to the west.
We observe celestial objects from the Earth. Since Earth rotates around the sun we see the celestial objects moving too. So basically due to the rotation of the Earth, celestial objects always seems to move from East to West.Hope that helped Of-course that must have helped, -Hailey xD LOL
Planets
No, the celestial sphere is a notional entity which is basically the "background" of stars against which the Sun, planets, etc., appear to move throughout the year. It is convenient for astronomical notation. The ancients used to believe there were some kind of spheres which stars and other celestial objects occupied and which was used to explain their movement.
One is mars. I don't know of any others. It appears to move backwards sometimes because the earth orbits closer to the sun than mars and we pass it up and then it catches back up to us
As the objects move farther apart, the gravitational force between them decreases. Every time the distance between them doubles, the force between them drops 75%.

What do objects snap to when you move them
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.
Objects move when their balance is changed.
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
planets appear to move
