Star in the constellation Lyra
Nu1 Lyrae (ν1 Lyrae) is astar in the northernconstellation ofLyra . Based upon an annualparallax shift of 2.69 mas as seen from Earth, it is located around 1,210 light years from theSun .[ 1] At that distance, the visual magnitude of the star is diminished by anextinction factor of 0.35 due tointerstellar dust .[ 6] With anapparent visual magnitude of 5.91,[ 2] the star is barely bright enough to be visible with the naked eye on a dark night.
This is a blue-white huedB-type subgiant star with astellar classification of B3 IV.[ 3] It is a suspectedvariable .[ 4] The star has nearly seven times themass of the Sun and, at an estimated age of about 40[ 3] million years, is spinning with aprojected rotational velocity of 145 km/s.[ 11] It radiates approximately 1460 times thesolar luminosity from itsphotosphere at aneffective temperature of 14,534 K.[ 8]
Nu1 Lyrae has five faint visual companions listed in theWashington Double Star Catalog , the nearest being a magnitude 13.0 star at anangular separation of 33.7 arc seconds along aposition angle of 76°, as of 2015.[ 13]
