Upsilon Librae will be the brightest star in the night sky in about 2.3 million years,[12] and will peak in brightness with an apparent magnitude of −0.46, or more than 40 times its present-day brightness.[12]
This star was originally designated by Bayer as Omicron Scorpii, but it was reassigned to Libra as Upsilon Librae.[13]: 196, 278 The star now known as Omicron Scorpii was a reinterpretation of o (Latin letter o) Scorpii, a designation given by Lacaille.
