67 Aquarii

January 01, 1970

67 Aquarii is a star located 484[1] light years away from the Sun in the zodiac constellation of Aquarius. 67 Aquarii is its Flamsteed designation.[9] It is a dim, blue-white hued star near the lower limit of visibility to the naked eye with an apparent visual magnitude of 6.40.[2] At the distance of this star, its visual magnitude is diminished by an extinction of 0.11 due to interstellar dust.[8] The position of this star near the ecliptic means it is subject to lunar eclipses.[10]

This is a late B-type main-sequence star with a stellar classification of B7.5 V,[4] which indicates it is generating energy through hydrogen fusion at its core. It is 316[8] million years old and is spinning rapidly with a projected rotational velocity of 205 km/s;[3] the critical velocity for this star is 377 km/s.[7] 67 Aquarii has 2.46[3] times the mass of the Suns and about double the Sun's radius.[6] It is radiating 42[3] times the luminosity of the Sun from its photosphere at an effective temperature of 10,257 K.[3]
