Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 1.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 172.6 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1105 years in a starship at a tenth of light speed.
- Distance. 111 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1915.
Saying hello
- Say hello. A radio message and its reply would take 221 years round-trip.

Why Tupi is a trash star
Tupi scores 11 points on Spacedle's rarity scale, which places it in the trash tier. Another 4 points would lift it into a rarer tier.
That score comes from 2 science badges — Star and Has a proper name — 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.
