Johannes Kepler
Under the Sun's gravity a planet follows an elliptical orbit that conforms to Kepler's laws of planetary motion. This was discovered at the end of the 1600s by Isaac Newton.
The ellipse is, with the sun at one focus of each planetary orbit.
The shape of the Earth's orbit around the Sun is called an "ellipse." This elliptical shape means that the distance between the Earth and the Sun varies throughout the year. The concept of an elliptical orbit is described by Kepler's First Law of Planetary Motion.
Each planet is in its own orbit and obey's Kepler's laws of planetary motion. Newton later discovered that the Sun's gravity is what makes the planets move in their orbits in the way they do.
No. A circle is an unstable shape for an object orbiting another. An orbit is between slightly and very elliptical (egg-shaped). If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit. Not quite as large as Mercury, but large enough.
It is called an ellipse.
Planets orbit in an ellipse.

Elliptical with the Sun at one focus.
The planetary orbit around the sun is the path which planets follow.This path is elliptical in shape and the Sun lies at one of the focal points of the ellipse.
An ellipse. (Kepler's first law of planetary motion) Since the plants do not orbit in a perfect circle. They orbit in a oval shape.
The ellipse is, with the sun at one focus of each planetary orbit.
Planetary orbits are eliptical. Each orbit forms an elipse.
Kepler discovered that the planets orbit the Sun in elliptical shapes, not in perfect circles as previously believed. This finding is summarized in Kepler's first law of planetary motion.

Johannes Kepler. Inspired Sir Isaac newton's discoveries.
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
