Trivia

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 824.6 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 73.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 469 years in a starship at a tenth of light speed.
  • Distance. 46.9 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1979.

Saying hello

  • Say hello. A radio message and its reply would take 93.8 years round-trip.

Why 111 Tau is a trash variable star

That score comes from 1 science badge — Variable 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.
