Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
- Packed system. Crammed into a system of five or more planets.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 21.2 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.9 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 12 thousand years in a starship at a tenth of light speed.
- Distance. 1205 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 821.
Saying hello
- Say hello. A radio message and its reply would take 2410 years round-trip.
Standing on it
- A year here. A full year lasts just 1 Earth days.
By the numbers
- Size. About 1.2× the width of Earth.
- Mass. Roughly 4460× Earth's mass — about 14 Jupiters.
- Your weight. You'd weigh about 3046.1× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. Around 781°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Kepler using the transit method.
Cosmic context
- Crowded system. One of at least 6 planets orbiting its star.

How to see it
Like any astronomical target, Kepler-80 f 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-80 f is an anomaly exoplanet
Kepler-80 f scores 86 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 9 points would lift it into a rarer tier.
That score comes from 8 science badges — Confirmed exoplanet, Earth-sized, Ultra-short period, Denser than iron, Multi-planet system, Richly packed system, 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.
