NGC 7332 is an edge-on peculiar lenticular galaxy[1][3] located about 67 million light-years away in the constellation Pegasus.[2] It possesses a (peanut shell)-shaped bulge, associated with stellar bar.[5] It was discovered on September 19, 1784 by the astronomer William Herschel.[6]
NGC 7332 and NGC 7339 form a dynamically isolated binary system (number 570 in the catalog of double galaxies compiled by Igor Karachentsev),[3] and are likely orbiting each other.[3] NGC 7332 is the brighter of the two galaxies.[3]
In the sky NGC 7339 lies 5' away from NGC 7332.[7] NGC 7332 is an unusually blue object with a corrected apparent B-magnitude of 11.5.[7] A 130mm to 200mm telescope will be needed to visually detect this pair of galaxies.[8] The two galaxies will appear at almost a right angle to one another.
