Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 2.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 235.1 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1506 years in a starship at a tenth of light speed.
  • Distance. 151 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1875.

Saying hello

  • Say hello. A radio message and its reply would take 301 years round-trip.

How we found it

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

Why Alrescha is a trash variable star

Alrescha scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.

That score comes from 2 science badges — Variable 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.
