One that the International expensive Union’s (IAU) needs for a celestial human body to be classified together a earth (or a dwarf planet) is the it orbits the Sun. Every one of the planets have various orbits, which impact many of the planets’ various other characteristics.
Since Pluto came to be a dwarf planet, Mercury is the earth with the many eccentric orbit. The eccentricity of an orbit is the measure of how various the orbit is from a one shape. If one orbit is a perfect circle, that eccentricity is zero. As the orbit becomes much more elliptical, the eccentricity increases. Mercury’s orbit ranges from 46 million kilometers native the sunlight to 70 million kilometers indigenous the Sun.
You are watching: Which planet has the least circular orbit
Venus, i beg your pardon is right next to Mercury, has the the very least eccentric orbit of any kind of of the planet in the Solar System. Its orbit ranges in between 107 million km and 109 million km from the Sun and has an eccentricity the .007 giving it a nearly perfect circle because that its orbit.
Earth also has a reasonably circular orbit v an eccentricity that .017. Planet has a perihelion of 147 million kilometers; the perihelion is the closest point to the sunlight in one object’s orbit. Our planet has actually an aphelion the 152 million kilometers. One aphelion is the furthest suggest from the sun in one object’s orbit.
Mars has one the the most eccentric orbits in our Solar mechanism at .093. That perihelion is 207 million kilometers, and also it has actually an aphelion the 249 million kilometers.
Jupiter has a perihelion of 741 million kilometers and an aphelion that 778 million kilometers. The eccentricity is .048. Jupiter bring away 11.86 year to orbit the Sun. Return this appears a lengthy time contrasted to the time our own planet takes to orbit, that is only a fraction of the moment of few of the various other planets’ orbits.
Saturn is 1.35 billion kilometers in ~ its perihelion and 1.51 exchange rate kilometers native the sun at its farthest point. It has actually an eccentricity that .056. Because it was an initial discovered in 1610, Saturn has actually only orbited the sunlight 13 times because it take away 29.7 year to orbit once.
Uranus is 2.75 billion mile from the sunlight at the closest suggest and 3 billion miles from the sunlight at its aphelion. It has actually an eccentricity of .047 and takes 84.3 year to orbit the Sun. Uranus has actually such an extreme axial tilt (97.8°) the rotates top top its side. This reasons radical alters in seasons.
Neptune is the furthest world from the sunlight with a perihelion of 4.45 exchange rate kilometers and an aphelion the 4.55 exchange rate kilometers. It has actually an eccentricity the .009, i beg your pardon is almost as low as Venus’ eccentricity. It takes Neptune 164.8 year to orbit the Sun.
