Trivia

What it actually is

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

Sense of scale

  • In perspective. Inside our stellar backyard: every radio broadcast humanity has ever made has already swept past it.

Find it in the sky

  • How to spot it. At magnitude 12.8 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Ursa Minor.
  • 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 April — 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. ≈ 1.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 133 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for HIP 66578 in the constellation UMi. At apparent magnitude 12.79, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, HIP 66578 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 66578 is a rare star

HIP 66578 scores 34 points on Spacedle's rarity scale, which places it in the rare tier. Another 16 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Never sets (northern circumpolar), White dwarf (a burnt-out core) and Blue-white star — 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.
