Why your planets revolve in elliptical orbit rather than circular orbit?
Circular orbits are unstable; any outside influence (i.e. other planets) will distort them. Elliptical orbits are self adjusting.
Do planets revolve faster around the sun in a certain location of the elliptical orbit?
Yes. The planets travel fastest at perihelion, the closest point to the sun in the orbit, and slowest at aphelion, the farthest point.
Which planets move in an elliptical orbit?
All the planets move with an elliptical orbit, but with a very low eccentricity.
What type of orbit do the planets have to revolve around the sun?
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.
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.
Do all planets revolve around the sun in an elliptical orbit?
Yes, every orbit is slightly elliptical ... see - nothings perfect!

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 revolve around the sun on an elliptical orbit and are called Wanderers?
the planets, the word planet comes from the latin word wanderer
Do planets revolve faster around the sun in a certain location of the elliptical orbit?
Yes. The planets travel fastest at perihelion, the closest point to the sun in the orbit, and slowest at aphelion, the farthest point.
Who is the astronomer that discovered planets revolve in an elliptical orbit?
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
Are the orbits of inner planets relatively closely spaced?
some times because we revolve in an elliptical orbit which is like the shape of an oval

Does the moon revolve round the planets?
Moons orbit planets Or rather moons and planets orbit their barycenter.
Do planets revolve around the sun at the same speed?
A planet has an elliptical shaped orbit. It orbits with a constant angular speed, but a varying linear speed.
