1E495

1E495 is a star located in the constellation of Cygnus, approximately 1,300 light-years away from Earth. It is a variable star, specifically a Mira-type variable, which means its brightness fluctuates over time. The star is classified as a red giant, indicating that it has exhausted the hydrogen in its core and expanded significantly in size. 1E495 is notable for its irregular pulsations, which can cause its brightness to vary by up to two magnitudes over a period of about 330 days. This variability is a characteristic feature of Mira variables, which are often used as standard candles in astronomy due to their predictable brightness changes. The star's spectral type is M7, which places it in the cool end of the red giant branch. Despite its distance, 1E495 remains an important object of study for astronomers, providing insights into the late stages of stellar evolution and the behavior of variable stars.
