Astronomy Science ~ Antares (α Scorpio / Scorpio Alpha) is a red supergiant star in the constellation of Scorpio in the Milky Way galaxy and the 16th brightest star in the night sky (sometimes listed as the 15th brightest). Together with Aldebaran, Spica, and Regulus, the star is one of the four brightest stars near the ecliptic.
And here are some interesting facts about the star Antares
1. Antares is 550 light years from Earth and the brightest star in the constellation Scorpio.
2. Antares is a system with two stars which consists of a red supergiant star Antares A and a smaller star but hotter Antares B.
3. Antares B 10 times larger than the Sun and 150 times brighter than our Sun, but because he was side by a very large parent star, causing Antares B can not be seen without a telescope.
4. Antares 10,000 times brighter than the sun.
5. The stars are big like Antares burn their fuel very quickly, as a result, they live a few million years.
6. Antares is currently about 12 million years old and nearing the end of his life and is expected to explode into a supernova in millions of years later.
7. Because the star color red as Mars, the ancient Greeks named Antares (same as-Ares) - ("equals-Mars"). However, some scholars have speculated that the star may have been named by Arabs prior to the Inter-name, or Antarah bin Shaddad, an Arab hero.
8. Antares A has a radius 850 times greater than the sun. If placed in the Solar System, the edge of this star will reach beyond the orbit of Mars.
9. Antares A is estimated to have a mass 18 times greater than the mass of the sun.
10. Antares A is estimated to have a surface temperature of about 3000C (5400 F), heat is only half of the hot sun.
