All planets orbit the Sun in an elliptical orbit. An elliptical orbit is defined as having an eccentricity of between 0 and 1. (0 is a circular orbit). Anything over 1 is defined as a hyperbolic orbit.
Mercury has the highest eccentricity of .205630 whereas the Earth has a near circular orbit with an eccentricity of 0.0167.
Triton, a moon of Neptune has lowest eccentricity with a value as close to 0 as can be measured.

Why is the gravitational force that the sun exerts on mercury not constant?
The orbit is not a perfect circle. Applies to all planets/asteroids/comets.
Is the earth's orbit around the sun a circle on an ellipse?
It is an ellipse. The orbits of all the planets are ellipses, though the orbit of Venus, while elliptical, is very close to being a circle.
What shape do planets trace as they orbit around the sun?
Planets orbit the sun in the shape of an ellipse, which is an elongated circle similar to an oval. When it was first discovered that the Sun is the center of the solar system, it was thought that all the planets had a circular orbit, but the calculations didn't fit.
What is the movement of earth and the other eight planets around the sun?
The most common type of orbit is a circle but depending on the size, mass, density of that planet and the orbit of others but the orbit so far found by Astromoners and Scientists alike are all circle based.In there title don't you mean What is the movement of earth and the other eight seven planets and many dwarf planets around the sun?
Kepler discovered that the orbit of each planet is an what rather than a perfect circle?
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.
How does planets circle around the Sun?
Planets circle in an elliptical orbit around the Sun.
Astronomer who discovered that planets orbit in an ellipserather than a perfect circle?
Kepler
What is planet Jupiter's orbit?
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
What planets orbit Jupiter?
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
What is the shape of the orbit of the earth and other planets?
Oval or elliptical shaped. (Not a perfect circle)
What is the name of the circle that the planets go around?
If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
What are the planets has the most elliptical and tilted orbit?
None of the planets orbit the sun perfectly in a circle, there is a degree of deviation from this perfect circle called eccentricity. The higher the eccentricity (more more the eccentric the orbit is) the further away from this perfect circle the orbit is. The planet that deviates most from a perfect circle, having the highest eccentricity, is Neptune. Neptune also has the highest axial tilt, tilted over onto its side as it orbits the sun.
What is mercury's orbit of the sun?
its orbit is not perfect circle, but is most eccentric of all planets,having eccentricity of 0.21 eccentricity means,the amount by which its orbit varies from perfect circle. 0 means circle and 1 means parabola. so mercury's eccentricity(0.21) is between circle and parabola, in fact, more closer to circle
Is Mars' orbit a perfect circle?
No planet's orbit is a perfect circle. They are all ellipses.
Why is the gravitational force that the sun exerts on mercury not constant?
The orbit is not a perfect circle. Applies to all planets/asteroids/comets.
Do all planets revolve around the sun in an elliptical orbit?
Yes, every orbit is slightly elliptical ... see - nothings perfect!
Is the earth's orbit around the sun a circle on an ellipse?
It is an ellipse. The orbits of all the planets are ellipses, though the orbit of Venus, while elliptical, is very close to being a circle.
