vdB 110

Set a site to see tonight's sky

When vdB 110 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

Dust grains scattering the light of nearby stars rather than emitting their own.

Class explainer for reflection nebula (catalogue type).

The facts

vdB 110 is a reflection / dark nebula in Ophiuchus. SIMBAD gives its distance as 231.385 pc (−0.8834 pc / +0.8834 pc) — ≈ 754.676 ly, measured by parallax from 2 measurements. The light reaching us from it now left it around the year 1271 CE. On the sky it spans 1.2′ — 4% of the full Moon's width. At that distance, that angle means it is roughly 0 light-years across.

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.
