The sun's gravity pulls the planets.
you
The gravitational pull between the planets and the sun keep the planets orbiting the sun all day everyday.
Pluto is the nineth planet from the sun, it is the farthest of the known planets. now it is proven that there are 3 more planets who knows it might be true!!! but Pluto is the ninth planet from the sun!!!!!!
the sun.
sun
The Sun pulls the planets around it
gravity
The sizes of the Sun and planets determine the strength of gravitational pull of the planets on each other and the Sun. The Sun's mass is so great that the planets can't escape from the Sun's pull and so as the planets are moving by the Sun pulls them back into orbit.
i know only one and it's a good one, the sun's gravity pulls the planets from flying some where else EDIT: Gravity pulls objects together and angular momentum makes sure planets orbit
the gravity of the sun pulls them in a circular motion.
The sun has the most gravity within the solar system, which pulls all the other planets towards itself. See, the gravity in outerspace is different; it pulls all the balls (planets) together because there is gravity on the sun (every part of the sun) and the spheres create a spinning motion. Since there is no planet exceeding the size and weight of the sun, the sun cannot revolve any planets.
Its because the gravitational field of the sun pulls the planets towards the sun and balances the intertia of the planets which make them want to move in a straight line.
Gravitational Pull?
Gravity from the sun pulls the planets near it and away from it ad away foer it
The Sun's gravity pulls on: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Gravity is a force that pulls the planets or a force to push. Gravity is on the Earth, gravity is floated in space. So the Sun's gravity keeps the planets to orbit the Sun.
because the stars gravity pulls them in and holds them in orbit
The movement of the planets (inertia) moves them perpendicular to the sun at about the same rate that the gravity from the sun pulls the planets in. The gravity of the sun is a little stronger as the earth is slowly, but continuously getting closer to the sun.
