S2-92 It is a large emission nebula visible in the constellation of the fox.

It is identified in the northern part of the constellation, on the border with the swan, on the southern edge of a very bright stretch of the Milky Way; It appears very extensive and weak, to the point that very sensitive tools are needed to be able to resume it. The best time for his observation in the evening sky goes from June to November; Its northern declination causes it to be more observable from the regions of the boreal hemisphere.

Sh2-92 is a very extensive H II region, whose diameter exceeds 200 light years; Perhaps it belongs to the outermost edge of the arm of Orion, at a distance of about 4400 parsec (14300 light years) from the Solar System. The source of the ionization of the gases of this cloud is a brilliant Wolf-rayet star, known with the abbreviation WR 127 (or HD 186943); this star, of apparent magnitude 10.18.
