NGC 2419

About image 

NGC 2419 is a globular cluster in the constellation Lynx, discovered by William Herschel on 1788.
It has apparent magnitude 9.06 and apparent dimension 6’; it is at a distance of about 300,000 light years from the Solar System and at the same distance from the galactic center.
NGC 2419 bears the nickname "the Intergalactic Wanderer," which was bestowed when it was erroneously thought not to be in orbit around the Milky Way, due to its great distance. Its orbit takes it further away from the galactic center than the Magellanic Clouds, but it can (with qualifications) be considered as part of the Milky Way. At this great distance it takes three billion years to make one trip around the galaxy.
