Planets move in elliptical orbits with the Sun at one focus.
Newtonian physics explains that gravity pulls the planets in toward the Sun but inertia provides the centripetal force to keep them in their elliptical orbit.
Einsteinian physics explains that space itself is warped by the mass of the Sun (and slightly by the lesser mass of the planets) each planet travels in a straight line in this warped spacetime.
If the planets did not move in their fixed orbits they may dash each other.
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
All the planets in our solar system move in elliptical orbits around the Sun. This means their orbits are not perfect circles, but rather slightly elongated shapes.
The planets orbit AROUND the sun, so technically not back and forth.
The planets around the sun move in a path called an orbit. This orbit is the result of the gravitational pull between the planets and the sun, causing them to travel in a curved path around the sun.
Planets move away by gravity not holding it together and also gravity holds planets together
The planets move on little circles that move on bigger circles.
Yes. All planets move in orbit around their host star.
planets appear to move
Apparent motion of the planets.
Planets naturally move in our sky over time and therefore are over different states.
If the planets did not move in their fixed orbits they may dash each other.
they move because of space eruptions
Because of the gravity
yes they do.
They move because of the gravitational pull of the sun.
The planets move in an act of gravity
