Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 243 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1556 years in a starship at a tenth of light speed.
  • Distance. 156 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1870.

Saying hello

  • Say hello. A radio message and its reply would take 311 years round-trip.

How we found it

  • Named. Notable enough to have earned a proper name, not just a catalogue number.

Why Secunda Hyadum is a common star

Secunda Hyadum scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 3 science badges — Star, Naked-eye visible 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.
