Comment

 North is to the bottom, I think it looks better upside-down.

NGC 2419 is a globular cluster in the constellation Lynx. NGC 2419 is often called the "Intergalactic Wanderer" because of its very remote distance from the center of our galaxy. It was discovered by William Herschel on December 31, 1788. NGC 2419 is at a distance of about 300,000 light years away from the solar system and at the same distance from the galactic center. Now confirmed to be a member of our galaxy, its orbit brings it further away from the galactic center than the Magellanic Clouds. At this great distance it takes three billion years to make one trip around the galaxy.
