Saturn and Vesta in Taurus

Explanation: Last November, while skygazing toward the constellation Taurus , astrophotographer Joe Orman arranged this time exposure to include the lovely Hyades and Pleiades star clusters in the field of his telephoto lens. A distance of 400 light-years for the close-knit Pleiades and 150 light-years for the V-shaped Hyades puts these clusters in the general galactic neighborhood of the Sun. Punctuating the Hyades' appearance, bright yellow Aldebaran , 60 light-years away, is not actually a member of the cluster, but it is Taurus' brightest star. Above Aldebaran a yellower, even brighter Saturn is is seen about 1.2 light-hours from our fair planet. Last and least massive , one of the faint specks below Aldebaran is main-belt asteroid Vesta, a mere 13 light-minutes away. Still cruising through Taurus, Vesta is steadily approaching a close alignment or conjunction with Saturn on March 19. Need a program to follow the players? Click on the image for a labeled version.
