Trivia
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.
- At 10% light speed. ≈ 119 years in a starship at a tenth of light speed.
- Distance. 11.9 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 2014.
Saying hello
- Say hello. A radio message and its reply would take 23.7 years round-trip.
Standing on it
- A year here. A full year lasts about 108 Earth years.
By the numbers
- Size. About 12.6× the width of Earth.
- Volume. About 2000 Earths could fit inside it.
- Mass. Roughly 2425× Earth's mass — about 7.6 Jupiters.
- Your weight. You'd weigh about 15.3× your Earth weight standing here.
- Temperature. A surprisingly temperate 2°C average.
How we found it
- Discovery. Found by La Silla Observatory using the radial velocity method.

How to see it
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 uncommon exoplanet
eps Ind A b scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Long-period world and Nearby (<25 ly) — 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.
