Antares (also known as Alpha Scorpii and Cor Scorpii) is a class M supergiant star, with a diameter of approximately 700 times Sol.
Description (Specifications)
Antares is approximately 600 light years from Terra. Visually, its luminosity is about 10,000 times that of Sol but overall, taking into account that the star radiates a considerable part of its energy in the infrared part of the spectrum the luminosity equals roughly 65,000 times (an absolute magnitude of -5.28). The mass of the star is calculated to be 15 to 18 sol masses. Its large size and relatively small mass give Antares a very low density.
- The Antares system also has a hot blue companion star (Antares B) at a distance of about 550 AUs of spectral type B2.5V. At magnitude 5.5, it is 1/370th as bright visually as Antares itself, yet still 170 times brighter than the Sun. The orbit has an estimated period of 850 years.
- Antares is the 16th brightest star as seen from Terra, it is the 38th brightest star in the galaxy, and one of the brightest in Charted Space. Antares is also the 10th largest star in the galaxy, and the largest in Charted Space.
- As seen from Vland or Capital/Sylea, Antares would be very bright at -1.58 Magnitude (brighter than Sirius from Earth).
