Sh2-112 è una nebulosa a emissione visibile nella costellazione del Cigno.

Si tratta di una regione H II circolare delle dimensioni apparenti di circa 15',
attraversata da una banda scura sul suo lato occidentale orientata in senso nord-sud.
Si ritiene che la stella responsabile della sua eccitazione sia BD+45 3216, una stella
blu doppia di classe spettrale O8V e una magnitudine apparente di 9,18; le stime
sulla distanza di questa stella forniscono un valore di 1740 parsec (circa 5670 anni luce),
che collocherebbe così Sh2-112 in una regione del Braccio di Orione particolarmente ricca
e fisicamente molto vicina al grande sistema nebuloso di Cygnus X. La nebulosa è posta in una
regione di formazione stellare di cui, secondo il catalogo Avedisova, farebbero parte anche alcune
sorgenti di onde radio e la nube molecolare [DBY94] 29, che possiede una massa di 1880 M⊙;
tuttavia in uno studio del 1994 si riporta per quest'ultima nube una distanza di 2100 parsec.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Dismissals Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
