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.
