Ananuca

Ananuca is a red dwarf star in the constellation of Vela. It is relatively nearby, with a distance of 30.7 light-years (9.4 parsecs) from Earth as measured from its parallax. It hosts three known exoplanets, Gliese 367 b, c & d. A red dwarf star, Gliese 367 is smaller, cooler, and much fainter than the Sun. It has 0.457 times the Sun's radius, an effective temperature of 3522 K, and a luminosity just 2.88% that of the Sun. Initial measurements from stellar isochrones suggested a young age of less than 60 million years old, but its orbit around the Milky Way is highly eccentric, unusual for a young star. It may have been forced into such an orbit via a gravitational encounter. However, a 2023 study, based on spectroscopic observations, found that its age should be much higher. Estimates from gyrochronology give an age in the range of 4.6 to 4.8 billion years.  Rotation-age relations suggest a value of 7.95±1.31 billion years.
