Trivia
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 11.2 you'll want a small backyard telescope, over in Draco.
- 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 March — 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. ≈ 739.2 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 65.7 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 421 years in a starship at a tenth of light speed.

How to see it
Look for GL GJ 3722 in the constellation Dra. At apparent magnitude 11.19, a small backyard telescope will bring it into view.
Like any astronomical target, GL GJ 3722 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 GL GJ 3722 is a trash star
GL GJ 3722 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.
