Barnard's Star and Mira are both well-known stars in astronomy. They are red dwarfs that belong to the Milky Way galaxy. However, Barnard's Star is a relatively nearby star, while Mira is a variable star known for its fluctuating brightness.

Mira is a binary star system, consisting of a red giant Mira A of spectral class M7 (Red) and a smaller main sequence star, Mira B, which falls into the slightly hotter stellar classification of K (Orange). The two stars are thought to be separated by around 100AU.

Stars like Mira are not living beings with a specific age. Instead, Mira is a variable star, meaning its brightness changes over time due to its pulsating nature. Mira is estimated to be around 6 billion years old, which is about half the age of our Sun.
As Mira is the brightest periodic variable that is not visible to the naked eye for part of its cycle, when Johannes Hevelius observed it, he named it "Mira" (meaning "wonderful" or "astonishing," in Latin) because it acted like no other known star.
A remarkable variable star in the constellation Cetus (/ Ceti).
Kori Bernards was born in 1953.
