NGC 7222


NGC 7222 is a large barred spiral galaxy with a ring structure, located in the constellation Aquarius. It is located 570 million light-years away from the Solar System and was discovered by German astronomer, Albert Marth on August 11, 1864.
NGC 7222 has a luminosity class of II and it has a broad H I line which contains regions of ionized hydrogen. NGC 7222 also has a surface brightness of 14.20 mag/am, which means it is considered a low [surface brightness galaxy]. LSBs are diffuse galaxies that have surface brightness one magnitude lower compared to the ambient night sky.
