The idea of planets orbiting the Earth in perfect circles is primarily associated with the ancient Greek philosopher Claudius Ptolemy. In his geocentric model, outlined in the "Almagest," Ptolemy proposed that celestial bodies, including planets, moved in circular orbits around the Earth, using epicycles to account for their observed movements. This model dominated astronomical thinking for many centuries until the heliocentric theories of Copernicus and later developments in astronomy.
The eccentricity of a planet's orbit describes how elliptical (or non-circular) the orbit is. It is a measure of how much the orbit deviates from a perfect circle. A value of 0 represents a perfect circle, while values closer to 1 indicate a more elongated orbit.
No, Mars' orbit around the Sun is not a perfect circle but is rather an elongated ellipse. This means that Mars' distance from the Sun varies throughout its orbit, with its closest point called perihelion and its farthest point called aphelion.
Earth - The planet we live on.
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
Gravity and Inertia. The gravity keeps the planet, moon etc. going in a circle and inertia keeps it going (inertia is the tendency of a moving object to continue in a straight line or a stationary object to remain in place. If there was no gravity the planet, moon etc. would just go in a straight line but with gravity it pulls it in a circle like a string attached to an object at the center.
A moon? I don't think a planet orbiting another planet would be called a planet.

It deviates from a perfect circle by a considerable amount.
A planet orbiting a star other than the Sun.An exoplanet is a planet orbiting any other star out there, except the Sun.
The orbit of a planet is an ellipse with the Sun at one of its foci. This means the shape of the orbit is similar to a slightly flattened circle. The orbiting planet will travel along this path due to the gravitational pull of the Sun.
No, Mars' orbit around the Sun is not a perfect circle but is rather an elongated ellipse. This means that Mars' distance from the Sun varies throughout its orbit, with its closest point called perihelion and its farthest point called aphelion.
A satellite is a body in orbit around another lager body. A probe is a machine sent to a specific place or specific course in space. Comment: That doesn't seem to answer the question. The curved path that a satellite follows is either a circle or an ellipse
Earth orbiting the sun is a planet that is attracted to a star.
There are no moons orbiting the planet Mercury.
Saturn does
No, Earth is a planet orbiting the Sun.
