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 5845 is a galaxy in Virgo. SIMBAD gives its distance as 29.65 Mpc — ≈ 96,710,000 ly from 6 measurements. The light reaching us from it now left it about 96.7 million years ago, while dinosaurs walked the Earth. SIMBAD measures it at 1.1′ × 0.8′ on the sky — 3% of the full Moon's width. At that distance, that angle means it is roughly 29,700 light-years across. Framing uses its catalogue size instead: 1.0′. It is receding from us at about 1,528 km/s (redshift z = 0.0051). Its morphological type is SA. 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.
