Yes, according to many scientists' theories, the sun is pulling the planets closer to it. JUST KIDDING! No idea really...
no because stars can orbit each other
Each planet has one orbit that is just called the orbit of . . . .
wilys
He discovered that avery planet has a ellipcial orbit, which means oval.
Each planet moves in a different orbit, at a different average distance from the sun, and at a different speed.
Ellipse.
Elliptical
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
The orbit of each planet it the path it takes as it rotates round the Sun under the influence of the force of gravity. Every planet has a separate orbit and the orbits all follow Kepler's three laws of planetary motion.
The eight planets are in order in their various places. If a planet is closer to the Sun, it will have a shorter orbit and therefore will take less time to complete its orbit. If a planet is farther away from the Sun, it will have a longer orbit and will take more time to complete its orbit. For example, Earth, the third planet from the Sun and takes just a year to revolutionize it, but since Uranus, the seventh planet, is farther away from the Sun, it will take 81 years to complete its orbit.
Kepler
The shape of the orbit of each planet is an ellipse. An ellipse is a geometric shape that is like a flattened circle. The Sun is located at one of the foci of the ellipse, not at the center.
