Trivia

What it actually is

  • What it actually is. A planetary nebula: the shed outer atmosphere of a dying Sun-like star, lit from within by the naked stellar core left behind.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 9.6 you'll want a small backyard telescope, over in Eridanus.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around November — 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. ≈ 69.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 6.2 million years even at the Parker Solar Probe's 192 km/s.

About NGC 1535

NGC 1535 is a rare nebula. It lies about 3,962.1 light-years from Earth, sits in the constellation Eri and shines at apparent magnitude 9.6.

A planetary nebula: the shed outer atmosphere of a dying Sun-like star, lit from within by the naked stellar core left behind.

How to see it

Look for NGC 1535 in the constellation Eri. At apparent magnitude 9.6, a small backyard telescope will bring it into view.

Like any astronomical target, NGC 1535 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 1535 is a rare nebula

NGC 1535 scores 48 points on Spacedle's rarity scale, which places it in the rare tier. Another 2 points would lift it into a rarer tier.

That score comes from 5 science badges — Nebula, Distant (over 1,000 light-years), Planetary nebula (a dying star's shell), Coming towards us and Its dying star is still visible — 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.
