NGC 2419

About image

NGC 2419 is a globular cluster visible in Lynx constellation, with a diameter of 4’ and a visual magnitude of 10.4.
It is called “the intergalactic wanderer” because of its peculiarity: it is in reality located 300000 light years away from the Milky Way center, well ouside the galactic halo where all the other globular clusters lay.

If we think that the Large Magellan Cloud is 160000 light years away, we immediately understand how remote is this cluster.
According to recent studies, NGC 2419 seems to be not a globular cluster, but the core of a dwarf galaxy.
