What is a Plutino?
Plutinos are a group of trans-Neptunian objects that have an orbit similar to that of Pluto. These objects are classified as resonant trans-Neptunian objects because they are in a 2:3 mean-motion resonance with Neptune, meaning that they complete two orbits around the sun for every three orbits Neptune completes. This resonance keeps them from colliding with Neptune over long periods of time.
Characteristics of Plutinos
Plutinos have a semi-major axis ranging from 39.3 AU to 47.7 AU, similar to that of Pluto's semi-major axis of 39.5 AU. They also have a moderate orbital inclination and eccentricity, with inclinations typically lower than those of classical Kuiper Belt Objects. Plutinos are mainly composed of rock and ice, similar to other objects in the Kuiper Belt.
Discovery and Naming
The first Plutino to be discovered was Pluto itself in 1930 by Clyde Tombaugh. Since then, numerous other Plutinos have been identified through telescopic observations. The term "Plutino" is derived from the name of the dwarf planet Pluto.
Notable Plutinos
One of the most famous Plutinos is 28978 Ixion, which was discovered in 2001. Another notable Plutino is 90482 Orcus, discovered in 2004. Both of these objects have been studied extensively to learn more about the characteristics of Plutinos and the broader trans-Neptunian population.
Conclusion
In conclusion, Plutinos are a fascinating group of trans-Neptunian objects that share orbital characteristics with Pluto. Studying these objects provides valuable insights into the formation and evolution of the outer solar system.
