Trivia

Could we get there?

  • Verdict. A multi-generation starship could one day attempt the crossing.

Getting there

  • Aboard Voyager 1. ≈ 184.3 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 16.4 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 105 years in a starship at a tenth of light speed.
  • Distance. 10.5 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 2016.

Saying hello

  • Say hello. A radio message and its reply would take 21 years round-trip.

How we found it

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

About Ran

Ran is an uncommon variable star. It lies about 10.5 light-years from Earth, sits in the constellation Eri, shines at apparent magnitude 3.72 and has spectral type K2V.

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

How to see it

Look for Ran in the constellation Eri. At apparent magnitude 3.72, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, Ran is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why Ran is an uncommon variable star

Ran scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 3 science badges — Variable star, Nearby (<25 ly) 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.
