NGC 4981

Set a site to see tonight's sky

When NGC 4981 is up, how long it stays usable and when it is in season all depend on where you observe from. Set your site and this page adds tonight's answer and its year.

The science

What you are looking at

In one sentence

A gravitationally bound system of stars, gas and dust.

Class explainer for galaxy (catalogue type). SIMBAD files it under 'GiG' (galaxy in a group).

The facts

NGC 4981 is a galaxy in Virgo. SIMBAD gives its distance as 21.3796 Mpc — ≈ 69,730,800 ly, measured by its redshift from 6 measurements. The light reaching us from it now left it about 69.7 million years ago, while dinosaurs walked the Earth. SIMBAD measures it at 2.9′ × 1.8′ on the sky — 9% of the full Moon's width. At that distance, that angle means it is roughly 57,900 light-years across. Framing uses its catalogue size instead: 2.7′. It is receding from us at about 1,675 km/s (redshift z = 0.0056). Its morphological type is SAB(r)bc. It shines at magnitude 11.4.

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.
