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 14 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Tucana.
- Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
- 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. ≈ 1.3 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 116.8 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 748 years in a starship at a tenth of light speed.

How to see it
Look for GL GJ 9791 in the constellation Tuc. At apparent magnitude 14, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, GL GJ 9791 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 9791 is a trash star
GL GJ 9791 scores 9 points on Spacedle's rarity scale, which places it in the trash tier. Another 6 points would lift it into a rarer tier.
That score comes from 2 science badges — Star and Intrinsically feeble (Mv > +12) — 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.
