What are the distinguishing features of the planet Orcus?

Orcus is a trans-Neptunian object located in the Kuiper Belt region of the outer solar system. It was discovered in 2004 and is classified as a dwarf planet. Orcus is known for having one of the largest known satellites, named Vanth, which was discovered in 2005.

Orcus has a number of distinguishing features. Firstly, it has a very elongated orbit which takes it from a distance of 30 AU from the Sun at its closest point to 48 AU at its furthest point. It has a very long orbital period of 246 years. Orcus is also known for having a reddish coloration, which is believed to be due to the presence of tholins on its surface. Tholins are organic molecules that are formed from the reaction of simple carbon-containing compounds under certain conditions, such as those found in the outer solar system.

Another distinguishing feature of Orcus is its large moon, Vanth. Vanth is thought to be about 1/3 the size of Orcus, making it one of the largest known satellites relative to its host body. Vanth has a much less elongated orbit than Orcus and is in a stable orbital configuration. The discovery of Vanth was important as it helped astronomers determine the density and mass of Orcus.

Orcus is a dwarf planet in the Kuiper belt, located in the outermost region of the Solar System. It was discovered in 2004 by Michael Brown of Caltech and his team. Orcus is about 900 kilometers in diameter, making it slightly larger than Pluto. It has a reddish color and a very dark surface.

Orcus has a moon, Vanth, which was discovered in 2011. Vanth is about 100 kilometers in diameter. It is the largest moon of any dwarf planet in the Kuiper belt.

Orcus is in a 2:3 orbital resonance with Neptune, which means that it orbits the Sun twice for every three orbits that Neptune makes. This resonance keeps Orcus from getting too close to Neptune.

Orcus has a very thin atmosphere, made up of nitrogen and methane. The atmosphere is so thin that it would not be able to support life.

Orcus is a very cold object. The average temperature on Orcus is about -220 degrees Celsius.

Orcus is a very interesting object. It is the largest dwarf planet in the Kuiper belt, and it has a moon that is larger than any other moon in the Kuiper belt. Orcus is also in a 2:3 orbital resonance with Neptune, which makes it very different from Pluto.

Here are some of the distinguishing features of Orcus:

• It is a dwarf planet.
• It is the largest dwarf planet in the Kuiper belt.
• It has a moon, Vanth, which is larger than any other moon in the Kuiper belt.
• It is in a 2:3 orbital resonance with Neptune.
• It has a very thin atmosphere.
• It is a very cold object.

Orcus is a very interesting object, and it is still being studied by scientists.
