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.)

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].
Which planet has most elliptical orbit?
Mars has the most elliptical orbit. The earth's is almost a perfect circle
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.
Which planet has an orbit that is closest to a perfect circle?
The earth's orbit is almost a circle, but not quite. It is elliptical, but the difference between the closest and farthest points is less than 4%. This is such a small difference that it would look like a circle to most people. Astronomy books often show misleadingly exagerated elliptical orbits.
Which planet has the largest elliptical orbit?
Planets are NOT elliptical in shape, they are basically spheres. However their spherical shape is distorted by the centrifugal forces resulting form their spin. This makes their equators fatter and their shape becomes that of an "Oblate Spheroid". All of the planets are spherical; none are appreciably oblate. In fact, being spherical is one of the elements of the 2006 IAU definition of "planet". Probably the biggest deviation from spherical is the mountain Olympus Mons on Mars; it is the highest mountain that we know of in the solar system. However, our exploration of Venus and Mercury are still in the very early stages; there are many surprises yet to be found there.
What is the shape of path of mercury planet around the sun?
Mercury has an elliptical orbit, it is also one of the most eccentric orbits of our solar system.
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].
Which planet has most elliptical orbit?
Mars has the most elliptical orbit. The earth's is almost a perfect circle
Which two planets has the most elliptical orbit?
The planet with the most elliptical orbit is Mercury. Second is Mars.
Where is most of the mass in the solar system and what effect does this have?
Most of the mass of the solar system is in the sun. As a consequence all objects in the solar system orbit the sun.
Where do most of the known asteroids have elliptical orbits?
Yes, just like all celestial body with a closed orbit. If you want to be specific, the orbit of the moon is spiral, since it is moving away from us at a pace of 3 cm per year.
What effect do these orbital resonances have on Io?
The orbital resonances cause Io to have an elliptical orbit which leads to tidal heating. Tidal heating makes Io the most volcanic object in our solar system.
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 do all the planets in our Solar system orbit?
Thay orbit jupiter because it has the most gravity and its the biggest
How come planets orbit the sun but not others?
If you mean "why don't they orbit other objects in our Solar System", the Sun has most of the mass in our Solar System.
