A portion of the dwarf planet Pluto's highly eccentric orbit brings it nearer to the Sun than Neptune, which has a nearly circular orbit.

The discovery of Sedna on a highly eccentric orbit beyond Neptune suggests a perplexing new population of icy bodies residing far outside the Kuiper Belt.

With a perihelion of 76 AU (more than twice that of Neptune), Sedna is well beyond the reach of the gas giants and unlike other Kuiper Belt Objects, could not be scattered into its highly eccentric orbit from gravitational interactions with Neptune alone.

Every 415.5 years, the comet Thatcher circles the Sun in a highly eccentric orbit shaped almost like a cat's eye.

The Fomalhaut team led by Kalas considers this circumstantial evidence that there may be other planet - like bodies in the system that gravitationally disturbed Fomalhaut b to place it in such a highly eccentric orbit.

It doesn't end there though, Earth has a almost circular orbit around the Sun, compared to Pluto's highly eccentric orbit.

The Fomalhaut team led by Paul Kalas (University of California, Berkeley) considers this circumstantial evidence that there may be other planet - like bodies in the system that gravitationally disrupted Fomalhaut b to place it in such a highly eccentric orbit.

A substellar companion at that distance would imply an orbital period of around a year, or it could be in a highly eccentric orbit with a much greater average distance from Proxima.

Comets, after all, spend most of their time far from their star and have highly eccentric orbits, which could account for the irregularity of dimming.

The same force can push dust into highly eccentric orbits, and even blow some of the smaller grains out of the disk entirely.

Traditionally, the solar system has been divided into planets (the big bodies orbiting the Sun), their satellites (a.k.a. moons, variously sized objects orbiting the planets), asteroids (small dense objects orbiting the Sun) and comets (small icy objects with highly eccentric orbits).

It therefore seems likely that exotic cases of highly eccentric orbits may be prominent in other solar systems, where various gaseous planets are known to exhibit large orbital fluctuations.

Using that as a guide, along with estimates of necessary runoff rates and the duration of valley network formation from other studies, Palumbo showed that model runs in which the Martian orbit was highly eccentric did indeed meet these criteria.

It has an eccentric orbit that is highly inclined with respect to the planets and takes it closer to the Sun than Neptune during a portion of its orbit.

Its orbit is highly eccentric (e = 0.71).

What Rhoden's team observed in their study was that during this process, several models predict that Charon's orbit around Pluto could have been highly eccentric, which would have caused severe tides on both celestial bodies, possibly leading to the formation of underground oceans of liquid water, similar to those that probably exist inside Europa.

While the mystery of KIC 8462852's brightness variations is still far from settled, a new study by a team of astronomers that has utilised NASA's Spitzer Space Telescope suggests that the culprit is most probably a huge swarm of cometary fragments that revolve around the star on highly elongated eccentric orbits.
