NGC 7222 is a large barred spiral galaxy with a ring structure, [1] located in the constellation Aquarius. [2] It is located 570 million light-years away from the Solar System [3] and was discovered by German astronomer, Albert Marth on August 11, 1864. [4]

Contents

NGC 7222 has a luminosity class of II and it has a broad H I line which contains regions of ionized hydrogen. [3] NGC 7222 also has a surface brightness of 14.20 mag/am, which means it is considered a low surface brightness galaxy (LSB). [5] LSBs are diffuse galaxies that have surface brightness one magnitude lower compared to the ambient night sky.

Supernova

One supernova has been discovered in NGC 7222 so far: SN 2008dr.

SN 2008dr

SN 2008dr was discovered by a team of astronomers; J. Leja, D. Madison, W. Li, and A. V. Filippenko from University of California, Berkeley as part of Lick Observatory Supernova Search (LOSS). [6] It had a magnitude of 16.8 and was located 1".3 west and 8".1 north of the nucleus. [7] [8] SN 2008dr was confirmed to be a Type Ia. [9] [10]
