NGC 4236 (also known as Caldwell 3) is a barred Magellanic spiral galaxy located in the constellation Draco.
The galaxy is a member of the M81 Group, a group of galaxies located at a distance of approximately 11.7 Mly (3.6 Mpc) from Earth.[3] The group also contains the spiral galaxy Messier 81 and the starburst galaxy Messier 82.[3] NGC 4236 is located away from the central part of the M81 group at a distance of 14.5 Mly (4.45 Mpc) from Earth.[4]
