A planet has a circular orbit, with the exception of pluto. A comet has a large but eliptical orbit. An asteroid has no orbit unless it becomes a moon. A meteor has no orbit. It usually flies in a straight line either burning up in the atmosphere or impacting on a planets surface. So, A comet.

∙ 8y agoMercury has the most eccentric orbit of the eight major planets. The Sun is about 20% from the centre of the orbit.
The minor axis of Mercury's orbit is 2.1% smaller than the major axis so it is very close to circular. This explains why it took so long to realise that the planets have elliptical orbits which are not just eccentric circles as the ancient theory assumed.

Which two planets has the most elliptical orbit?
The planet with the most elliptical orbit is Mercury. Second is Mars.
An oval like shape that is used to describe the orbit of planets?
Mars, and all the other planets, have oval-shaped, or eliptical, orbits.
What is the shape of mercury's orbit?
Yes. It varies in distance from the sun. At closest it is about 46,000,000 km and at farthest, 69,800,000 km away. It is the most elliptical orbit of the solar system planets, the measure of which is eccentricity. Mercury is 0.205. Zero is a circle higher numbers are more elliptical, with 0.999... as the limit.All planets have elliptical orbits.
What is Mercury's eccentricity?
All the planets have elliptical orbits, but Mercury and Mars have the greatest eccentricity. As to why Mercury's orbit is the most eccentric may be related to its proximity to the Sun.
How are the planets held in orbit?
Most people don't think this but planets are actually held in orbit by gravity. With out gravity the planets will fall down.
Which two planets has the most elliptical orbit?
The planet with the most elliptical orbit is Mercury. Second is Mars.
Do most planets orbit in an elliptical patern?
Yes.
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.
An oval like shape that is used to describe the orbit of planets?
Mars, and all the other planets, have oval-shaped, or eliptical, orbits.
When does Neptune orbit the Sun fastest?
Neptune orbits the Sun (as do most planets) with an elliptical orbit. When the orbit takes the planet closest to the Sun it is moving faster than when it is furthest from the Sun when on an elliptical orbit.
What shape does an orbit take?
It varies from planet to planet. But most planets including our own, orbit the star in an elliptical motion.
Name of the orbit around the sun?
The SHAPE of the orbit the Earth and most planets and other bodies of mass in space are usually elliptical.
Which planet has most elliptical orbit?
Mars has the most elliptical orbit. The earth's is almost a perfect circle
Which planet has an oblique elliptical orbit?
Pluto has the most oblique orbit. All the planets have elliptical orbits, however Mercury has the most elliptical orbit since Pluto is now considered a dwarf planet. This information is provided by the Royal Astronomical Society of Canada and available online [see related links].
What is the motion of planets 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.
How far is jupliter from the sun?
740,573,600 km at its closest, and 816,520,800 km at its furthest point - like most of the planets, it follows an elliptical orbit.
What is the most elliptical orbit in the solar system?
Planets: Of the planets, Mercury has the distinction of having has the smallest axial tilt of any of the planets (about 1⁄30 of a degree) and the largest orbital eccentricity (0.205). "Eccentricity" (e) is the mathematical measure of how far an ellipse is from being a circle. A circle has e = 0. The maximum value of e for an ellipse is just less than 1 (or "unity"). Comets: Comets are often said to have highly elliptical orbits and the highest eccentricity possible for an object to still be in a closed orbit is just less than unity. Most comet have eccentricities close to unity. An object that enters the inner solar system once and never returns may not be in a closed (elliptical) orbit at all. It could have a "hyperbolic" orbit. So, the most elliptical orbits in the solar system are those of comets with eccentricities of near unity. (Notice that this question is about elliptical orbits only.)
