- Theta Scorpii (Wikipedia)
Theta Scorpii (θ Scorpii, abbreviated Theta Sco, θ Sco) is a binary star in the southern zodiac constellation of Scorpius. The apparent visual magnitude of this star is +1.87, making it readily visible to the naked eye and one of the brightest stars in the night sky. It is sufficiently near that the distance can be measured directly using the parallax technique and such measurements obtained during the Hipparcos mission yield an estimate of approximately 329 light-years (101 parsecs) from the Sun.
- Iota-1 Scorpii (stars.astro.illinois.edu)
IOTA-1 SCO (Iota-1 Scorpii). Supergiants are rare, and to find two of them within a quarter-degree of each other is rarer still. To find two forms of supergiants that for the class are rare in themselves draws the eye, or at least should. Nevertheless, these two magnificent stars, which have no proper names and are known as Iota-1 (the western and brighter) and Iota-2 Scorpii, are quite neglected, perhaps by contrast to Scorpius’s brighter magnificent stars, which include one of the most prominent of all supergiants, Antares.
