Trivia

Hard to believe

  • Messier object. One of the 110 showpieces of the Messier list — catalogued as M39.

What it actually is

  • What it actually is. An open cluster: a few hundred stars born together out of one collapsing cloud, still drifting along in loose formation.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.
  • Sense of scale. Gravity is not strong enough to hold it. Within a few hundred million years these siblings will be scattered right around the galaxy.

Find it in the sky

  • How to spot it. At magnitude 4.6 you can see it with your own eyes from a dark site, over in Cygnus.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around August — that's when to go looking.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

About NGC 7092

NGC 7092 is an epic cluster. It lies about 977.3 light-years from Earth, sits in the constellation Cyg and shines at apparent magnitude 4.6.

An open cluster: a few hundred stars born together out of one collapsing cloud, still drifting along in loose formation.

How to see it

Look for NGC 7092 in the constellation Cyg. At apparent magnitude 4.6, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, NGC 7092 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why NGC 7092 is an epic cluster

NGC 7092 scores 57 points on Spacedle's rarity scale, which places it in the epic tier. Another 21 points would lift it into a rarer tier.

That score comes from 7 science badges — Star cluster, Messier object, Bright deep-sky object, Open cluster, Big on the sky, Coming towards us and Bright enough for the unaided eye — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
