Class explainer for galaxy (catalogue type).

The facts

NGC 2985 is a galaxy in Ursa Major. SIMBAD gives its distance as 22.90 Mpc (−5.72 Mpc / +5.72 Mpc) — ≈ 74,690,000 ly, measured by the Tully–Fisher relation from 1 measurement. The light reaching us from it now left it about 74.7 million years ago, while dinosaurs walked the Earth. SIMBAD measures it at 4.0′ × 3.3′ on the sky — 13% of the full Moon's width. At that distance, that angle means it is roughly 87,100 light-years across. Framing uses its catalogue size instead: 3.6′. It is receding from us at about 1,288 km/s (redshift z = 0.0043). Its morphological type is Sab. It shines at magnitude 10.5.

Sky maths: apparent positions with refraction, one-minute steps; usable = full astronomical dark, at least 30° up and clear of your skyline. Survey images: CDS, Strasbourg (DSS2 and other surveys). Science: SIMBAD. The hours, heights and Moon on this page use no weather forecast; the rank is this target’s place in the Targets list, whose score also counts the cloud forecast when there is one.
