Real Life Information
Eta Cassiopeiae is a binary star system that exists in real life and is located in the constellation Cassiopeia. It is approximately 19.42 light-years away from Earth, making it one of the nearest star systems to our own. The system is composed of two stars, Eta Cassiopeiae A and Eta Cassiopeiae B, which orbit each other in a period of approximately 480 years.
Eta Cassiopeiae A, also known as Achird, is the primary star in the system. It is a yellow dwarf star, similar to our own Sun, and is classified as a G-type main-sequence star. With an apparent magnitude of +3.46, it is visible to the naked eye from Earth. The star has about 81% of the Sun's mass and 79% of its radius. Its surface temperature is estimated to be around 5,310 Kelvin, slightly cooler than the Sun.
The secondary star, Eta Cassiopeiae B, is a red dwarf star and is classified as a K-type main-sequence star. It is much fainter and smaller than its companion, with an apparent magnitude of +7.51, making it invisible to the naked eye from Earth. The star has about 57% of the Sun's mass and 66% of its radius. Its surface temperature is estimated to be around 4,100 Kelvin.
The Eta Cassiopeiae system is of particular interest to astronomers due to its proximity to Earth and the similarity of Eta Cassiopeiae A to our Sun. This makes it a valuable system for studying stellar evolution and the dynamics of binary star systems. The system is also a popular target for amateur astronomers due to the brightness of Eta Cassiopeiae A and the challenge of observing the fainter Eta Cassiopeiae B.
The Eta Cassiopeiae system has been the subject of several studies searching for extrasolar planets. However, as of now, no planets have been confirmed in the system. Despite this, the system remains a target of interest for future planet-hunting missions due to the potential habitability of planets that could exist in the system.
In popular culture, Eta Cassiopeiae has been featured in several works of science fiction. For example, in the "Star Trek" universe, Eta Cassiopeiae is the location of the planet Andoria, home of the Andorian species.
