Details:
The two bright, orange "stars" in this image are the planet Mars (right) and the star Antares (Alpha Scorpii). The Roman god Mars was known as Ares to the Greek. Antares is a Greek name, meaning "counterpart of Ares" (Anti-Ares), as the star appears to the eye to have both brightness and color similar to the planet.
In reality, Mars is a compareably small planet (with about half the diameter of the Earth), whereas Antares is a red supergiant star: If one would put Antares in the center of our solar system, the orbits of the planets Mercury, Venus, Earth and Mars would lie inside the star!
Single 30 second exposure, taken with a Canon EOS 550D at ISO 800, 33mm, f/3.5, Cokin P830 diffusor. Tracked with the Vixen Polarie star tracker.
