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 11.5 you'll want a small backyard telescope, over in Aquarius.
- Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
- 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. ≈ 1.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 140.1 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 897 years in a starship at a tenth of light speed.

How to see it
Look for GL GJ 4159 in the constellation Aqr. At apparent magnitude 11.46, a small backyard telescope will bring it into view.
Like any astronomical target, GL GJ 4159 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 4159 is a trash star
GL GJ 4159 scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.
That score comes from 3 science badges — Star, On the zodiac and Deep red 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.
