A perfect circle means the planet is a perfect sphere (very unlikely) and no other gravitational force other than the body at the center of the orbit affecting its rotation.
In our Solar System, there are many things that will interfere with that. (like the moons and other planets)
It's not an impossible situation, but it's VERY unlikely.
All planets revolve around the Sun.
Planets 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According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus.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.
Johannes Kepler stated that the planets revolve around the sun in an ellipse.
No all planets revolve around the nearest star. In our case, the sun.
no, all the planets revolve AROUND the sun.
The planets revolve around the sun because of the sun's gravitational pull. The larger the object is the more gravitational pull it has therefore the planets revolve around the sun and the moon revolves around the Earth.
The Sun.
They revolve.
Yes, all of the planets rotate around the sun, in the same direction but at different speeds and time periods. well planets rotate on their own axis, the correct term would be revolve. The planets revolve around the sun
the sun's gravity
Yes, every orbit is slightly elliptical ... see - nothings perfect!
