Rho Lupi

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.

[14] With an age of just 44[7] million years, the star is spinning with a projected rotational velocity of 166 km/s.

[7] This is giving the star an oblate shape with an equatorial bulge that is an estimated 6% larger than the polar radius.

It is radiating 365[9] times the solar luminosity from its outer atmosphere at an effective temperature of 15,947 K.[7]
