Orbits sould be circular because the centripetal force that keeps objects in circular motion is constant (it is gravity!)
Venus has the almost circular orbit.
circuitous path orbit
No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.
An eliptical orbit. In theory a planet could also have a circular orbit, but no planet that we know of has a perfectly circular orbit, although some have a nearly circular orbit.
A circular orbit would have an eccentricity of 0, meaning the orbit is perfectly circular with no deviation. Eccentricity is a measure of how elongated an orbit is, ranging from 0 to 1, with 0 indicating a circle and 1 indicating a parabolic orbit.
An elliptical orbit is a non-circular orbit where the orbiting object follows an elongated path around another object.
The earths orbit around the sun is almost circular.
The velocity in a circular orbit changes all the time. The acceleration is towards the center.
circular
It is not in the plane of the ecliptic and is sometimes inside the orbit of Neptune
The circular orbit equation used to calculate the motion of objects in a circular path is called the centripetal force equation, which is F mv2/r.
The circular path is known as an orbit.
