mu2 Sco b: A Giant Planet Orbiting a Hot, Young Star

mu2 Sco is a B2 IV star with one known planet, mu2 Sco b. The host star is very young, with an age of 0.02 billion years, and has a mass of 9.1 solar masses and a radius of 5.6 solar radii. Its temperature is 21700 K. The star's reported mass estimate is larger than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.

mu2 Sco b was discovered by imaging in 2022. Its reported mass estimate is 4580 Earth masses. That mass estimate is larger than Earth's and roughly 14.4 times Jupiter's mass. No orbital period is reported for mu2 Sco b.
