NGC 5683 is a type S0-alenticular galaxy with a bar[1] located in theBoötes constellation.[2] It is 513 millionlight-years away from theSolar System[3] and has an approximatediameter of 256,000 light-years meaning it is larger compared to theMilky Way.[3] NGC 5683 was discovered byGeorge Johnstone Stoney on April 13, 1850.[4]
NGC 5683 happens to lie near to a spiral galaxyNGC 5682, but they are far apart from each other. Nearby is another galaxyNGC 5689.[5]
NGC 5683 has anactive galactic nucleus which presents strong x-rays.[6] It is aSeyfert 1 type galaxy[7][8] and such falls into theMarkarian catalogue as Mrk 474, which its core shines inultraviolet rays.[9] The most accepted theory for this energy source of active galactic nuclei is the presence of anaccretion disk around itssupermassive black hole. It also shows high amounts of strong emission-lines which are mostly attributed to short-lived star formation in its regions likely restricted to a nuclear disk with its radius less than few hundred parsecs.[10]
Type la supernova SN 2002db[11] was discovered on May 18, 2002, in NGC 5683 by a collaboration ofastronomers andReiki Kushida from LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches).[12] It was positioned 8 arcsecs west and 9 arcsecs north of the nucleus, with amagnitude of 17.6.[13]
