"Lion's forehead", a corruption of the Arabic word Al Jabha. Actually a magnificent binary star lying 8 degrees SSE of Regulus, with yellow-orange components of 2.2mag (lum. 90 Suns) and 3.5mag (lum. 30 Suns) at a distance of 4.4", in contrast to each other they can be seen as far as green. Their mutual orbital period is estimated at 619 years. As recently as 1782, when this attractive double star was first discovered by William Herschel, the arc distance of its components was less than 2". Since then, the distance has increased significantly, reaching nearly 4.4" by the end of the 20th century. |
