Orcus is a probable dwarf planet located in the distant Kuiper Belt.

This intriguing object is known as the “anti-Pluto” because its orbit is nearly identical to Pluto's but is positioned in the opposite phase, meaning when Pluto is closest to the Sun, Orcus is furthest away.

With a diameter of 595 miles, Orcus is similar in size to Ceres. It also has a large moon named Vanth, which is about one-third the size of Orcus.

The solar system is full of interesting objects akin to Orcus.
