The star, which goes by the designation 2MASS J18082002-5104378 B, also challenges the assumption that the first stars in the
Universe were large, exclusively high-mass and short-lived stars. In addition, its location within the usually active and crowded disk
of our galaxy is unexpected. Gemini Observatory
2MASS J18082002-5104378 (abbreviated J1808-5104) is an ultra metal-poor (UMP) binary star system, in the constellation Ara,
about 1,950 ly (600 pc) from Earth, and is a single-lined spectroscopic binary (SB1). It is one of the oldest stars in the universe,
about 13.53 billion years old, possibly one of the very first stars, a star made almost entirely of materials released from the Big Bang.
A tiny unseen companion, a low-mass UMP star, is particularly unusual.
