The orbit of planets in our solar system are ellipses with the sun as a focus. Use the formula for eccentricity to determine the eccentricity of the imaginary planet s orbit.

The eccentricity of the orbit of the planet below is 0 8 and the value of c is 20.
Planets eccentricity of orbit. Such eccentricity is sufficient for mercury to receive twice as much solar irradiation at perihelion compared to aphelion. Earth s orbital eccentricity is less than 0 02. An eccentricity close to 1 means the orbit is extremely elongated.
These variations affect the distance between earth and the sun. The orbit of pluto is the most eccentric of any planet in our solar system. Mercury has the greatest orbital eccentricity of any planet in the solar system e 0 2056.
An ellipse has two foci which are the points inside the ellipse where the sum of the distances from both foci to a point on the ellipse is constant. Eccentricity measures how much the shape of earth s orbit departs from a perfect circle. The eccentricity of an orbit is a single number between 0 and 1 which describes how stretched out the orbit is.
Before its demotion from planet status in 2006 pluto was considered to be the planet with the most eccentric orbit e 0 248. The earth has one of the least eccentric orbits at 0 017 though venus and neptune are even more circular. Most of the planets have eccentricities close to 0 so they must have orbits which are nearly circular.
Many comets have extremely eccentric orbits. Halley s comet for instance has an orbital eccentricity of almost 0 97. If e 0 the orbit is a circle.
Other trans neptunian objects have significant eccentricity notably the dwarf planet eris 0 44. The planets are generally not especially eccentric. The key point is that the eccentricity cannot change.
The sun is not at the center of an elliptical orbit. For example this graph shows the eccentricities of. Orbital periods are also given in units of the earth s orbital period which is a year.
Zero means the orbit is perfectly circular. Over time the pull of gravity from our solar system s two largest gas giant planets jupiter and saturn causes the shape of earth s orbit to vary from nearly circular to slightly elliptical. Planet eccentricity eccentricity is the deviation of a planet s orbit from circularity the higher the eccentricity the greater the elliptical orbit.
In a two body system the orbit can have any eccentricity you want. Only comets coming from the outer reaches of the solar system get close to this value. In fact almost all the planets are.
In a three or many body system the bodies perturb each others orbits and the eccentricity can change with time. The eccentricity e is a number which measures how elliptical orbits are. Pluto s orbital eccentricity is almost 0 25.
