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 11.4 you'll want a small backyard telescope, over in Capricornus.
- 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. ≈ 327.5 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 29.1 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 186 years in a starship at a tenth of light speed.

How to see it
Look for HIP 103039 in the constellation Cap. At apparent magnitude 11.41, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 103039 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 103039 is an uncommon star
HIP 103039 scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Nearby (<25 ly), On the zodiac, Deep red 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.
