Trivia

What it actually is

  • What it is made of. Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.

Sense of scale

  • In perspective. Inside our stellar backyard: every radio broadcast humanity has ever made has already swept past it.

Find it in the sky

  • How to spot it. At magnitude 4.7 you can see it with your own eyes from a dark site.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around August — that's when to go looking.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 208.5 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 18.5 thousand years even at the Parker Solar Probe's 192 km/s.

About eps Ind A b

eps Ind A b is an epic exoplanet. It lies about 11.9 light-years from Earth, shines at apparent magnitude 4.69, has spectral type K5 V and has an equilibrium temperature near 275 K.

Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.

How to see it

At apparent magnitude 4.69, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, eps Ind A b 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 eps Ind A b is an epic exoplanet

eps Ind A b scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 23 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Nearby (<25 ly), Gas giant, Long-period world, Its star is visible to the naked eye and Two suns in its sky — 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.
