Antares

I chose this star because it is estimated to be 17 times more massive and 10,000 times more luminous than the Sun, so despite being about 600 light years from Earth, it can be seen with the naked eye. I found this super interesting. It is a red supergiant and it is the seventeenth brightest star and the brightest star in the constellation Scorpius. It also composes the group known as the "Royal stars of Persia"-- four stars that the ancient Persians believed guarded the four districts of heaven.
