NGC 2146 (also known as the Dusty Hand Galaxy[2]) is a barred spiral galaxy type SB(s)ab pec in the constellation Camelopardalis. The galaxy was discovered in 1876 by Friedrich August Theodor Winnecke.[3]
It has a diameter of 80,000 lyr.[3] The galaxy's most conspicuous feature is the dusty lanes of a spiral arm lying across the core of the galaxy as seen from Earth, the arm having been bent 45 degrees by a close encounter with a smaller galaxy possibly NGC 2146a about 0.8 billion years ago.[3] This close encounter is credited with the relatively high rates of star formation that qualify NGC 2146 as a starburst galaxy.[3]
It has been host to two known supernova events:
