HD 137058 is a star in the southern constellation of Lupus. Eggleton and Tokovinin (2008) list it as a single star, although Nitschelm and David (2011) noted it may be a double-lined spectroscopic binary. Its apparent visual magnitude is 4.60, which is bright enough to be visible to the naked eye. Based upon an annual parallax shift of , it is located 240 light years away.
The stellar classification of the primary component is A0 V, matching an A-type main-sequence star. It is spinning rapidly with a projected rotational velocity of 300 km/s, giving it an oblate shape with an equatorial radius 22% larger than the polar radius. The star is radiating 156 times the Sun's luminosity from its photosphere at an effective temperature of 8,178 K.
