}}{{Starbox end}}Rho Lupi, Latinized from ρ Lupi, is a solitary[19] star in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 4.05.[3] Based upon an annual parallax shift of 10.32 mas as seen from Earth, it is located about 316 light years from the Sun. It is a member of the Upper Centaurus Lupus subgroup of the nearby Scorpius–Centaurus Association.[21]This is a B-type main sequence star with a stellar classification of B3/4 V.[4] It is a microvariable with a period of 10.7 hours and an amplitude of 0.0046 in magnitude.[23] With an age of just 44[12] million years, the star is spinning with a projected rotational velocity of 166 km/s.[12] This is giving the star an oblate shape with an equatorial bulge that is an estimated 6% larger than the polar radius.[26] It has an estimated 4.66[12] times the mass of the Sun and about 3.4[13] times the Sun's radius. It is radiating 365[14] times the solar luminosity from its outer atmosphere at an effective temperature of 15,947 K.[12] References1. ^1 {{citation | title=XHIP: An extended hipparcos compilation | last1=Anderson | first1=E. | last2=Francis | first2=Ch. | journal=Astronomy Letters | volume=38 | issue=5 | pages=331 | year=2012 | bibcode=2012AstL...38..331A | doi=10.1134/S1063773712050015 | arxiv=1108.4971 | postscript=. }}
