Otherwise, the planetary system is too compact to be affected by even a stellar companion on a very eccentric orbit.
Because gravitational interactions between planets are responsible for such peculiar orbits, the astronomers suspect that the dive of the missing planet toward the star before it became a giant could have given the surviving massive planet a burst of energy, throwing it into an eccentric orbit like a boomerang.
Farrell speculated that a companion star traverses a very eccentric orbit around the black hole.
he measurements were made while Mars Express was at altitudes of between 275-330 km above the Tharsis volcanic 'bulge' during the closest points of its eccentric orbit, and were combined with data from NASA's Mars Reconnaissance Orbiter.
Scientists have realized that Nereid, Triton's satellite sibling, is unusual too because it has a highly eccentric orbit, taking it 1.
Pluto, the only solar system planet yet to be explored by NASA, has a highly eccentric orbit averaging nearly six billion kilometers away from the Sun.

Pluto clearly shows seasonal variations owing to its relatively eccentric orbit and its unusual axial tilt of 120[degrees].
Ordinarily, Pluto lies farthest from the sun, but at the moment Pluto's eccentric orbit as carried it inside Neptune's.
The Fomalhaut team led by Kalas considers this circumstantial evidence there may be other planet-like bodies in the system that gravitationally disturbed Fomalhaut b to place it in such a highly eccentric orbit.
What makes the observation even more exciting to scientists is that the planet has a comet-like eccentric orbit, carrying it as close as 2.
