Spacecraft that orbit around Earth do so in two types of orbits: circular and elliptical. In a circular orbit, the spacecraft is always at the same distance from the center of the Earth.

ABSTRACT: This paper investigates the chaotic behavior of an electrodynamic tethered satellite system (ETSS) orbiting Earth in an inclined elliptical orbit. The system is modelled using a dumbbell ...

But at its farthest point, it travels over 1,600 times farther than Earth. So, it has a very elliptical orbit. This orbit places 2017 OF201 among a class of objects known as extreme trans ...

To put that into perspective, Neptune orbits at approximately 30 AU. This enormous elliptical orbit makes 2017 OF201 an extreme trans-Neptunian object (ETNO), a group that contains bodies living ...
