LDN 262

Set a site to see tonight's sky

When LDN 262 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

Cold dust dense enough to block the light of whatever lies behind it.

Class explainer for dark nebula (SIMBAD classification).

The facts

LDN 262 is a reflection / dark nebula in Sagittarius. SIMBAD gives no distance for it, so its true size and light-travel time can't be worked out here. SIMBAD measures it at 9.0′ × 2.0′ on the sky — 29% of the full Moon's width. Framing uses its catalogue size instead: about 6.4′, estimated from the cloud's catalogued area.

For scale

Angular size, as it would sit on your sky.

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.
