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 9.2 you'll want a small backyard telescope, over in Cassiopeia.
- 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 October — 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. ≈ 45.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 4 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 25.9 thousand years in a starship at a tenth of light speed.

How to see it
Look for HIP 5984 in the constellation Cas. At apparent magnitude 9.22, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 5984 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 5984 is a trash star
HIP 5984 scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Distant (over 1,000 light-years) 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.
