All the planets have orbits so four cannot be picked out.
ALL closed gravitational orbits are ellipses.
The orbit of the planets in our Solar system are not perfectly circular, but eliptical. Each planet also has its own unique orbit, no two planets share an identical orbit. Because of the elliptical (oval) orbit of planets some get close to each other or cross the path of another planet's orbit.
He was a tireless and perhaps rather obsessive observer, who mapped out and documented the coordinates of many of the stars and planets year after year, which Kepler than used after Brahe's death to discover the fact that the planets in fact go around the sun in eliptical orbits.
The orbits of the planets all lie in nearly the same plane for preservation of angular momentum.
Mars, and all the other planets, have oval-shaped, or eliptical, orbits.
Planetary orbits are eliptical, that is they are shaped as elipses. All planets revolve around the sun anti-clockwise as viewed from Earth's north pole.
The orbits of the planets, including Mars, are eliptical, not circular. Keplers observed positions did not fit a circular orbit. The differences led him to discover that the orbits were not circular, but eliptical.
all orbit according to the sun's gravity- if there was none they would all move in a pretty straight line instead of an orbit Answer: All planets follow eliptical orbits around the sun, and all move in the same direction around the sun.
Because the diameters of the orbits are different. Some are closer to the sun, others are further out.
These small pertubations are what keep the choas of there stable orbits. It's all planned out, the universe I think has found a way.
Not by the scientific community, but his extensive data was used by Keppler to figure out that planets had eliptical orbits. this led to kepplers laws of planetary motion.
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
Johannes Kepler.
All the planets have orbits so four cannot be picked out.
No, because all planets known have elliptical orbits.
The planets orbits are the routes or paths that the planets follow around our sun. One orbit is one trip around the sun (one year).
