Sky position and adopted distance
Eagle Nebula is placed at J2000 RA 18.3 h, Dec -13.8° in Serpens, at an adopted distance of 7,000 light-years.
Also known as M16, Messier 16, IC 4703, NGC 6611.
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.

Eagle Nebula (star-forming emission nebula; central source NGC 6611, young ionizing star cluster): measured footprint 70 × 55 light-years; display depth 12 light-years (not measured); outer radius used for arrival 35 light-years.
The 70 × 55 light-year footprint, named feature positions, and Pillars model follow published observations. The NASA Pillars mesh is an authored scientific visualization, not a tomographic gas map. The surrounding cloud thickness and anonymous emission samples are constrained presentation choices because the full line-of-sight density is not measured.
