Star in the constellation Mensa
Eta Mensae , Latinized from η Mensae, is the Bayer designation for a solitary,[ 4] star in the southern constellation of Mensa . This object has an apparent visual magnitude of 5.47,[ 2] parallax shift of 4.88 mas as seen from Earth,[ 1] light years from the Sun .
This is an evolved K-type giant star with a stellar classification of K4 III.[ 3] Sun's luminosity from its photosphere at an effective temperature of 4,055 K.[ 7] infrared excess that suggests the presence of circumstellar dust.[ 10] [ 11] Hyades cluster .[ 12]
