What is the difference between the earth's orbit and a comet's orbit?
The Earth orbits in the plane of the ecliptic in an ellipsoidal orbit that is nearly circular. Comets orbits are highly elliptical and mostly out of the plane of the ecliptic.
What is the shape of the path of a planet around the sun called?
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.
What is the shape of the orbits of the planets around the sun?
The planetary orbits of our solar system are considered "elliptical." This includes "circular" orbits, as a circle is a type of ellipse. In astrodynamics, an elliptical orbit and a circular orbit both fit into the description of a Kepler Orbit.
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.
How did Johannes Kepler figure out that the planets had an elliptical orbit?
The circular orbits that were being used at the time to model the solar system did not quite work with mathematical predictions or observations. Kepler found that elliptical orbits provided more accurate predictions of where the heavenly bodies would appear in the sky.
What are the planets with the most circular orbits?
Venus has the least eccentric (most nearly circular) orbit of the eight in our solar system.
What does eccentricity mean to an astronomer?
A bodies eccentricity is a measure of how circular the orbit of that body is. Perfectly circular orbits have the lowest eccentricity, of 0, whereas orbits such as that of the dwarf planet Pluto are more eccentric. When there are multiple large bodies in an orbit, with smaller bodies orbiting multiple of these, the eccentricities of the smaller bodies are quite high.
Even though orbits are ellipes what shape is a typical planet's orbits most like?
Planetry orbits are elliptical. Most planet's orbits are nearly circular apart from Mercury and Pluto.
Is Pluto really a moon that floated away from Saturn?
Almost certainly not. Pluto is a member of a large group of bodies called KBOs (Kuiper Belt Objects) and is probably a left-over planetesimal from early in the Solar System's formation. Current theories suggest that Pluto and other bodies like it (called Plutinos) originally had nearly circular orbits, but were thrown into their current resonance orbits with Neptune due to a relatively sudden movement of Neptune which perturbed them, throwing some of them into highly elliptical orbits.
Planets do not collide into one another?
Planets around the sun in nearly circular orbit . The radii of these orbits differ widely

Planet 's orbits are nearly circular .what shape is a comet's?
All orbits are geodesic curves. Comets tend to have elliptical orbits ... as do planets, really; the degree of eccentricity (this is a measure of how "stretched" the ellipse is) just tends to be higher for comets.
Do comets have highly elliptical orbits around the sun?
Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact. Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.

Are the orbits of natural and artificial satellites elliptical?
Yes. In the special case, they may be circular, or nearly so. A circle is a special case of an ellipse.
What are nearly round bodies whose orbits cross other planet's orbits?
Dwarf Planets are bodies that both orbit the sun directly and which are large enough to be approximately spherical in shape. They are not the dominant objects in their orbit though, crossing other orbits of other large bodies. If they were to be found not to do this, being the dominant body at that orbit, then they would be classed as a planet.
