A planetary body is a non-luminous object rounded by it's own gravity that orbits a star or a stellar remnant. A moon, or satellite, orbits a planetary body.

They are in the shape of an ellipse.

No, all the planetary orbits are elliptical.

ALL planetary orbits are ellipses.
"Planetary orbits" is the technical term.
Planetary orbits that are elliptical will have a greater focus.

There is no reason why any number of bodies can't exist in orbits that exactly coincide with the earth's orbit. Since the process of planetary formation is completely random, however, the odds are against it, and no other body has ever been discovered sharing the earth's orbit.
a planetary satellite is any object that orbits a planet
Yes
A satellite is an object which orbits a larger body. For example, the Moon orbits the Earth, and the Earth orbits the Sun. The Moon is a satellite of the Earth and the Earth is a Satellite of the Sun.
He suggested the orbits were circles.
