Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 131.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 11.7 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 75 thousand years in a starship at a tenth of light speed.
- Distance. 7503 light-years from Earth.
Look-back time
- Look-back time. Its light left before the last ice age ended.
Saying hello
- Say hello. A radio message and its reply would take 15 thousand years round-trip.
Standing on it
- A year here. A full year lasts just 49.8 Earth days.
By the numbers
- Size. About 5.9× the width of Earth.
- Volume. About 209 Earths could fit inside it.
- Mass. About 29.5× the mass of Earth.
- Your weight. You'd weigh about 0.8× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 182°C on average.
How we found it
- Discovery. Found by Kepler using the transit method.

How to see it
Like any astronomical target, Kepler-943 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 Kepler-943 b is a common exoplanet
Kepler-943 b scores 22 points on Spacedle's rarity scale, which places it in the common tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Neptune-like, Found by Kepler and Distant (>1000 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.
