Trivia

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 3.8 you can see it with your own eyes from a dark site, over in Carina.
  • Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
  • Best time of year. It stands highest in the middle of the night around January — that's when to go looking.

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 23.8 million years at Voyager 1's speed (17 km/s).

About NGC 2516

NGC 2516 is a rare cluster. It lies about 1,352.3 light-years from Earth, sits in the constellation Car and shines at apparent magnitude 3.8.

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 2516 in the constellation Car. At apparent magnitude 3.8, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, NGC 2516 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 2516 is a rare cluster

NGC 2516 scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.

That score comes from 6 science badges — Star cluster, Distant (over 1,000 light-years), Bright deep-sky object, Open cluster, Big on the sky 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.
