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 11.7 you'll want a small backyard telescope, over in Hercules.
- Northern sky. It rides the northern half of the sky — an easier target the further north you are.
- Best time of year. It stands highest in the middle of the night around June — 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. ≈ 2.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 257.9 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1651 years in a starship at a tenth of light speed.

Why HIP 90190 is a trash star
HIP 90190 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.
