Delta Lupi

In traditional Chinese astronomy, it is "the 2nd (star) of the Cavalry Officer" (騎官二).

The distance to this star has been measured using the parallax technique, yielding an estimate of roughly 900 light-years with a 15% margin of error.

It is radiating around 10,000 times the luminosity of the Sun from its outer atmosphere at an effective temperature of 23,000 K, giving it a blue-white hue.

This star has nearly 12 times the mass of the Sun and is roughly 15 million years old.

[8] Delta Lupi is a Beta Cephei variable star that undergoes periodic pulsations.
