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]
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.
