Trivia
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 8.5 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Cepheus.
- 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.
Getting there
- Aboard Voyager 1. ≈ 11.2 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 990.8 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 6345 years in a starship at a tenth of light speed.

Why HD 213224 is a trash star
HD 213224 scores 7 points on Spacedle's rarity scale, which places it in the trash tier. Another 8 points would lift it into a rarer tier.
That score comes from 2 science badges — Star and Never sets (northern circumpolar) — 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.
