Shown in its true colour — like most stars, it is too far away to photograph as more than a point of light.
Alpha Lupi, also named Uridim, is a binary star, and the brightest star in the southern constellation of Lupus. According to the Bortle Dark-Sky Scale, its apparent visual magnitude of 2.3 makes it readily visible to the naked eye even from highly light-polluted locales. Based upon parallax measurements made during the Hipparcos mission, the star is around 460 light-years from the Solar System. It is one of the nearest supernova candidates.
