GRAVITY...
gravity means that objects are "attracted" to other objects, and the larger the object, the more GRAVITY will "attract" the object. The sun's gravity is too large for the planets to overcome.
the sun does not move, the planets orbit around the sun idiot.
The planets orbit the Sun. The Sun is at the center of our solar system and does not move.
The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
Yes. All planets move in orbit around their host star.
they orbit the sun
orbit
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
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.
"orbit"
All the planets move with an elliptical orbit, but with a very low eccentricity.
Moons are approximately spherical objects which orbit planets and are smaller than the planets that they orbit, although they are still relatively large objects (so an orbiting dust particle does not qualify as a moon). Since moons orbit planets, their motion around the solar system is controlled by the planets that they orbit; planets orbit the sun, and planets take their moons with them.
No, planets do not move around the sun in perfect circles. Instead, they follow elliptical orbits, which are elongated circles. This means that the distance between a planet and the sun varies as it moves along its orbit.
