Most of the time it varies only slightly from magnitude 3.2. But every 8.2 years the bright component is eclipsed by its companion star, causing the system's total light to drop to about 4.0. The next of these eclipses is expected in October 2012.
Antares (Alpha Scorpii) is a red supergiant star in a binary system with a hotter blue main-sequence star Antares B. Antares B can therefore be termed a hot companion of the cool supergiant.
