Known Extreme Outer Solar System Objects

.

Figure 1: The Sun is the yellow dot in the center. The orbits of Jupiter, Saturn, Uranus and Neptune are shown by purple solid circles. The Kuiper Belt is shown by the dotted light blue region. Sedna's orbit is shown in orange while 2012 VP113's orbit is shown in red. Both objects are currently near their closest approach to the Sun. They would be too faint to detect when in the outer parts of their orbits. Notice that both are far away from the giant planet and Kuiper Belt regions. (Credit: Scott S.

q - The perihelion distance (closest approach to the Sun).
a - The mean semi-major axis.
i - The mean inclination.
e - The mean eccentricity.
Peri - The Argument of Perihelion.
Node - The Longitude of the Ascending node.
Long - The Longitude of Perihelion.
M - The mean anomaly.
Period - The time of one revolution around the Sun.
mag - The optical magnitude of the object (R-band).
H - The absolute magnitude of the object.
Size - The estimated diameter of the object.

Stable - Shows if the object had a stable orbit for billions of years
in a simulation using the Sun and the known giant planets Jupiter,
Saturn, Uranus and Neptune (see Sheppard and Trujillo 2016 for
details).  Resonance suggests the object's semi-major axis shows signs
of being in a resonance with the giant planets.
