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 does the eccentricity of the earths orbit compare to the eccentricity of the other planets?
The Earth's orbit has a relatively low eccentricity compared to some other planets in our solar system. For example, Mercury and Mars have more eccentric orbits than Earth. Venus and Jupiter have orbits that are almost circular, with very low eccentricities.
Which equation should be used to find the eccentricity of the earths orbit?
Eccentricity is the measure of how much the conic section diverges into its circle form. One of the formulas for eccentricity is e=c/a this formula can be used to get the eccentricity of the ellipse.
What is the shape of the orbits of most members of the solar system?
round but some rounder than others. Every object is in an orbit which is an ellipse. The planets are in orbits which look almost exactly like circles with an offset centre, but some comets and dwarf planets have orbits with a high eccentricity.
What shapes are the orbits of many comets?
Most cross orbits of planets which allows it to hit the planets easier. They do not go into a full orbit at all.
What 2 planets have the most cicular orbits?
Venus has an eccentricity of 0.00677323 Neptune has an eccentricity of 0.00858587 Triton, a moon of Neptune, orbit is as close to a perfect circle with an eccentricity of 0.000016 The Earth for comparison has an eccentricity of 0.01671022
Which planet has an orbital eccentricity most like the orbital eccentricity of the earth?
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859
Which planet's orbit is most nearly circular?
Venus has the most nearly circular orbit of all the planets in our solar system. Its eccentricity, a measure of how elongated an orbit is, is only 0.0067, making it almost circular compared to other planets like Mercury or Mars.
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.
What type of orbit do the planets have to 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.
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.
What are all of the planet's orbit from 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 does the eccentricity of the earths orbit compare to the eccentricity of the other planets?

What are the planets has the most elliptical and tilted orbit?
None of the planets orbit the sun perfectly in a circle, there is a degree of deviation from this perfect circle called eccentricity. The higher the eccentricity (more more the eccentric the orbit is) the further away from this perfect circle the orbit is. The planet that deviates most from a perfect circle, having the highest eccentricity, is Neptune. Neptune also has the highest axial tilt, tilted over onto its side as it orbits the sun.
Which equation should be used to find the eccentricity of the earths orbit?
Eccentricity is the measure of how much the conic section diverges into its circle form. One of the formulas for eccentricity is e=c/a this formula can be used to get the eccentricity of the ellipse.
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.
What shape are the paths of the planets around the sun?
Kepler's laws of planetary motion, which have been around for 400 years, say that a planet's path or orbit has the shape of an ellipse as a result of the Sun's inverse-square gravitational force. The shape of an ellipse is measured by its eccentricity factor, which expresses how far each focus is from the centre (the Sun is always at one focus). A circle is a special case of an ellipse with zero eccentricity. The eight planets have orbits with low eccentricity, so the best way to draw a planetary orbit is to draw a circle with a pair of compasses. Apart from Mercury, Mars has the most eccentric orbit, with eccentricity of 9%, which means that the minor axis of the ellpise is only 0.4% smaller than the major axis. The other six planets have less eccentricity and orbits which are even more nearly circular.
