Mu Arae Alpha

Mu Arae is a fifth magnitude (5.15) class G (G3) subdwarf-dwarf (implying it has given up core hydrogen fusion or is about to) that lies at a distance of 50 light years. Its temperature of 5813 Kelvin and luminosity 1.7 times that of the Sun leads to a radius 1.3 times solar and reveals a mass 10 percent greater than that of the Sun. Like the majority of planet-holding stars, Mu Arae is metal-rich, with an iron content (relative to hydrogen) that is double solar. The star rotates more slowly than the Sun, with a period of about 27 days.

Mu Arae Alpha orbits in 9.55 days, has a mass at least 0.03 times that of Jupiter (only 10 times that of Earth, one of the lowest mass-limits known), and is 0.09 Astronomical Units (AU) from the star (13.5 million kilometers, 8 million miles, or 23 percent Mercury's distance from the Sun). As expected for such a close planet, the orbit is circular.

As always...
