For more details:

According to one source, this HII region, which is most likely ionised by a B2.5 V class star, lies at the edge of a 1000 solar mass molecular cloud in a similar direction to the Sh 2-192 to Sh 2-194 group of nebulae.

According to a 2007 paper by Russeil, Sh 2-196 may lie at the same distance as Sh 2-192 and Sh 2-193 (2400 +/- 320 parsecs), however she has identified a possible O9.5 class ionising star with a photometric distance of 5670 +/- 590 parsecs, suggesting that it may be much further away than the other nebulae.
