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.
The mutual gravitational forces that attract a planet and the sun to each other are responsible for keeping the planet in orbit around the sun.
The shape of a comet's orbit is called an ellipse. This shape is a sort of narrowed circle and comets move in this shape around the sun.
Kepler discovered that the orbit of each planet is an ellipse rather than a perfect circle. The planet with an orbit that is closest to a circle is Venus.
The size of the planet along with the gravitational force within the planet.
Elliptical
This orbit is called an ellipse. An oval shape.
The shape of a planet's orbit is elliptical.

Each planet has one orbit that is just called the orbit of . . . .
It varies from planet to planet. But most planets including our own, orbit the star in an elliptical motion.
