Since soon after the Big Bang, all objects in the universe have been moving away from each other and there is no fixed point which can be used as a fixed frame of reference against which the earth's motion can be measured.
There are various components to earth's motion which are known. It moves in an orbit which is approximately an ellipse with the centre of mass of the earth-sun pair at one of the foci. However, it is perturbed from this elliptical orbit by the gravitational effect of the other bodies in the solar system. In addition, the earth is moving through space along with the whole solar system, as the sun orbits the centre of the Milky Way Galaxy at around 800,000 km per hour. To that motion, it is necessary to add the motion of the Milky Way Galaxy towards the Andromeda Galaxy: these are approaching each other at approx 432,000 km per hour.
From space but not earth.
I wouldn't say there are "different theories"; after all, the movement of Earth in space is very well understood.Among other things, Earth rotates about once a day (at a speed of about half a kilometer per second, at the equator); it orbits the Sun once a year at a speed of about 30 km/second, and the entire Solar System orbits the Milky Way at an even greater speed, taking over 200 million years for one full orbit.
The main theories about the shape of the Earth are the spherical Earth theory, which posits that the Earth is a sphere, and the flat Earth theory, which incorrectly suggests that the Earth is flat. The spherical Earth theory is supported by scientific evidence such as images of the Earth from space and the way ships disappear over the horizon.
yes because the earth moves
the gravity moves the Earth in a circle
an orbit
The stars usually don't move much, but earth moves a lot. Since star are in view from the earth at any sight direction, the earth rotating, and revolving gets the earth viewing different parts of space from different places. It moves gradually, so the star seem to move.
The earth's center of gravity is the center of the earth, or the center of the mass with the mass being the earth. The earth spins as it moves through space on account of sun's gravitational forces and because there is nothing in space to get in the way or stop the earth from rotating.
The Earth moves around the sun due to the warping of space time that we perceive as gravity.
Space is different from earth because space has no gravitation, earth has gravitation
The constellations appear to change their position in the night sky due to the Earth's rotation. As the Earth spins on its axis, different constellations become visible at different times of the night and year. This apparent movement is known as the diurnal motion of the stars.
Gravity Einsteins theories of relativity say the mass of the earth bends space, and so although we ARE thrown off, we follow bent space back to Earth.
