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 has an orbital eccentricity most like the orbital eccentricity of the moon?
Saturn.
The planet has an orbital eccentricity most like the moon?
Saturn
Which planet s orbital shape would be most similar to Jupiters orbital shape?
Jupiter's orbit is an ellipse with an eccentricity of 0.048, which means that it looks like a circle with the Sun off-centre by an amount equal to 0.048 times the average radius. Uranus has an eccentricity of 0.047 and that is the closest among the other planets.
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.
How is the orbital path of a comet like the orbital path of the planets?
All orbits are ellipses; this is true for both planets and for comets. Cometary orbits are somewhat extreme ellipses, where the difference between the perihelion (closest to the Sun) is very different from the aphelion (farthest from the Sun) distance. This difference is called "eccentricity". Planets have relatively low eccentricity; for Earth, for example, the eccentricity is only 3%. Some comets don't have an "orbit" at all. An "orbit" implies that the comet will eventually come back. But some comets are "hyperbolic"; their paths aren't an ellipse, but a hyperbola. A hyperbolic comet is a one-time visitor to the solar system; it has fallen in from interstellar space, and will be going back out to interstellar space.

What planet has a year 687 earth days long?
Uranus which has an orbital period of 84.016846 years which is 30,687.153 days.
Why does mercury take 88 days to revolve in the sun?
This is a lot like asking: Why does the earth take 365 days to revolve around the sun ? Here's an answer, which I'm sure you'll find evasive and unsatisfying, and so it is. But when you ask "why", it really puts us out of the realm of the science, and into the philosophical realm. Kepler demonstrated, and Newton proved, that the orbital period of a light object revolving around a much more massive object under the influence of gravitation is completely determined by the dimensions of the orbit. In the case of the sun as the large central body, an average distance of 93 million miles with small eccentricity produces an orbital period of 365.25 earth days, and an average distance of 36 million miles with small eccentricity produces an orbital period of 88 earth days. 88 days is Mercury's orbital period, because 36 million miles is its distance from the sun. A grain of sand, a rock, a glob of dust, a space ship, a comet, or a planet, at the same distance from the sun, would all have an orbital period of 88 earth days.
What orbit shape is Mercury?
Mercury's orbit, like all planet's, is elliptical.The eccentricity of Mercury's orbit is 0.206
What planet has the lowest eccentricity of orbit in the solar system?
The plane of the Earth's orbit IS the ecliptic, so by definition, Earth has the lowest inclination to the ecliptic at "zero". But Neptune is the next lowest at 0.77 degrees, and Jupiter next at 1.31 degrees.
Does a dwarf planet orbit another planet?
No. A planet-like object that orbits a planet is a moon. A dwarf planet orbits a star just like a true planet does, but has been unable to clear its orbital path of debris such as asteroids and comets.
Is the planet Saturn like earth?
No, its very different in lots of ways. Its much colder, it has a longer orbital period of the sun, it has a different composition (no solid surface), and is also much bigger.
Do planets with moons have eclipses as often as earth?
Planets with moons may indeed have Earth-like eclipses. Eclipses happen when moon orbital plane intersects with planet orbital plane with respect to its star. Eclipses can only happen however if angular diameter of the moon is similar to (or greater than) angular diameter of star as seen from planet's surface, which is quite a rare condition. In the whole Solar System moon-eclipses only happen on Earth.
