Palomar 2
Palomar 2 is a globular cluster located in the constellation of Auriga. It's part of a group of 15 globulars known as the Palomar Globular Clusters, discovered in survey plates from the first National Geographic Society – Palomar Observatory Sky Survey in the 1950s. However, Palomar 2 is one of the most obscured since we see it dimmed by nearly 3 full magnitudes as it lies behind the Perseus Arm and Norma/Outer Arm of the Milky Way.
