Open Cluster NGC2419

NGC 2419 (also known as Caldwell 25) is a globular cluster in the constellation Lynx. It was discovered by William Herschel on December 31, 1788. NGC 2419 is at a distance of about 300,000 light years from the solar system. NGC 2419 got the name "the Intergalactic Wanderer," which was bestowed when it was thought not to be in orbit around the Milky Way. Its orbit brings it further away from the galactic center than the Magellanic Clouds. At this great distance it may take three billion years to make one trip around the galaxy. The cluster is dim to the earth observer. Nonetheless, NGC 2419 is a 9th magnitude object and is readily viewed, in good sky conditions, with good quality telescopes as small as 102mm (four inches) in aperture. Intrinsically it's one of the brightest and most massive globular clusters of our galaxy, having an absolute magnitude of -9.42 and being 900,000 times more massive than our Sun.
