Sh2-112 è una nebulosa ad emissione visibile nella costellazione del Cigno, nella parte settentrionale della costellazione, a circa 1,5 ° a NO della stella brillante Deneb.
È una regione H II circolare di dimensioni apparenti di circa 15 ‘, attraversata da una fascia scura sul lato occidentale orientata in direzione nord-sud. Si ritiene che la stella responsabile della sua eccitazione sia BD + 45 3216; le stime della distanza di questa stella forniscono un valore di 1740 parsec (circa 5670 anni luce), che collocherebbe quindi Sh2-112 in una regione del braccio di Orione particolarmente ricca e fisicamente molto vicina al grande sistema nebuloso di Cygnus X.
Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.
It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.
It is a circular H II region of apparent size of about 15′, crossed by a dark band on its western side oriented in a north-south direction. It is believed that the star responsible for its excitation is BD+45 3216; estimates of the distance of this star provide a value of 1740 parsec (about 5670 light years), which would place so Sh2-112 in a region of the Orion Arm particularly rich and physically very close to the great nebulous system of Cygnus X.
