NGC 2363 is a star-forming region in the Magellanic galaxy NGC 2366 which is located in the constellation Camelopardalis. It contains NGC 2363-V1, a luminous blue variable star which is 6,300,000 times more luminous than the Sun and one of the most luminous stars known. It can be seen in this Hubble Space Telescope image as the bright isolated star in the dark void on the left of the nebula.[3]
