Trivia

What it actually is

  • Spectral class. Its spectrum reads DF — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

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 9.9 you'll want a small backyard telescope, over in Cassiopeia.
  • Never sets. So far north that from Britain, Canada or northern Europe it never dips below the horizon — it is up every clear night of the year.
  • Best time of year. It stands highest in the middle of the night around October — that's when to go looking.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 440.2 thousand years even at the Parker Solar Probe's 192 km/s.

About HIP 10267

HIP 10267 is an uncommon star. It lies about 281.9 light-years from Earth, sits in the constellation Cas, shines at apparent magnitude 9.94 and has spectral type DF.

Its spectrum reads DF — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

How to see it

Look for HIP 10267 in the constellation Cas. At apparent magnitude 9.94, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 10267 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 HIP 10267 is an uncommon star

HIP 10267 scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.

That score comes from 3 science badges — Star, Never sets (northern circumpolar) and White dwarf (a burnt-out core) — 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.
