Also known as Altarf or Beta Cancri, Tarf is the brightest star in the Cancer constellation. It lies between Gemini and Leo and is the faintest constellation of the Zodiac; its brightest star, Beta Cancri, is of magnitude 3.5. Asellus Australis marks the famous open star cluster Praesepe, also known as the Beehive Cluster, or Messier 44. The surface gravity on this star has been estimated at around 1.5 cgs. This means that it is also a Barium star, a type of cool giant showing enhanced abundances of barium in its spectrum. Tarf / Beta Cancri is the brightest star in the zodiacal constellation of Cancer, the celestial crab. Since Tarf’s exact age and mass aren’t known, it is quite difficult to predict its future. Its brightest star, Al Tarf, is fourth magnitude, though in its favor (at 3.59) it is just over the line from third. The system has a combined apparent magnitude of +4.74, making it faintly visible to the naked eye. Tarf is quite a cool star, much cooler than our Sun, having surface average temperatures that reach 3,990 K. Its companion star is a red dwarf of the fourteenth magnitude. If applicable, the Mass and Radius is measured in Jupiters. The second star is more far and is about 65 times the distance of Pluto from sun which means its orbital period is 76,000 light years.
