IC 2087

LBN 813

Set a site to see tonight's sky

When IC 2087 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

The facts

IC 2087 is an object in Taurus, catalogued as LBN 813. SIMBAD gives its distance as 144.816 pc (−3.4121 pc / +3.4121 pc) — ≈ 472.326 ly, measured by parallax from 2 measurements. The light reaching us from it now left it around the year 1554 CE. On the sky it spans 4.0′ — 13% of the full Moon's width. At that distance, that angle means it is roughly 1 light-years across.
