I can tell you that it is not a circle.
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 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.
An eliptical orbit. In theory a planet could also have a circular orbit, but no planet that we know of has a perfectly circular orbit, although some have a nearly circular orbit.
A year. Each planet in a solar system has a year of different length, equal to the time it takes for one complete orbit around its sun.
The plane with the smallest orbit is Mercury, and the planet with the largest orbit is Neptune.
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.

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.

This orbit is called an ellipse. An oval shape.
