What evidence do you have that planets move around the sun in an elliptical orbit?

That theory is supported by observation, and is predicted by other theory that is
confirmed by both observation and experiment.
1). A system of planets moving around the sun in elliptical orbits is the simplest structure
that produces the motions of the planets that we actually see in the sky.
(demonstrated by Kepler, working with Tycho's observational data)
2). A theory of universal gravitation, proportional to the product of masses and inversely
to the square of the distance between masses, predictsthat planets will move around
the sun in elliptical orbits.

All of the planets in our solar system have an elliptical orbit around the sun.
What planet moved in an elliptical orbit?
All planets have elliptical orbits.
Which two planets has the most elliptical orbit?
The planet with the most elliptical orbit is Mercury. Second is Mars.
The planets orbit the sun in what?

How does planets circle around the Sun?
Planets circle in an elliptical orbit around the Sun.
Do all planets revolve around the sun in an elliptical orbit?
Yes, every orbit is slightly elliptical ... see - nothings perfect!
Which planets move in an elliptical orbit?
All the planets move with an elliptical orbit, but with a very low eccentricity.
What keeps planets in elliptical orbits?
Gravity and velocity (inertia) keeps planets in orbit around suns.
What has elliptical orbits?
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
What is the orital shape of the planets in our solar system?
All of the planets in our solar system have an elliptical orbit around the sun.
What is the shape of the orbit that the planets take called?
Elliptical Orbit
Why is Johann Kepler famous?
He is a danish astronomer who stated that all the planets revolve around the sun in elliptical orbits and that the sun is not in the exact center of the orbit.
What planet moved in an elliptical orbit?
All planets have elliptical orbits.
Which two planets has the most elliptical orbit?
The planet with the most elliptical orbit is Mercury. Second is Mars.
Why did Copernicus think that stars are farther from earth than the planets are?
He knew that the planets revolved around the sun in an elliptical orbit.
The planets orbit the sun in what?
In an elliptical orbit. E.g. not entirely round.
