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 12.8 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Indus.
- Southern sky. It rides the southern half of the sky — an easier target the further south 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. ≈ 5.1 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 452.3 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 2897 years in a starship at a tenth of light speed.

How to see it
Look for HIP 109115 in the constellation Ind. At apparent magnitude 12.75, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, HIP 109115 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 109115 is a trash star
HIP 109115 scores 3 points on Spacedle's rarity scale, which places it in the trash tier. Another 12 points would lift it into a rarer tier.
That score comes from 1 science badge — 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.
