Trivia

What makes it special

  • 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. ≈ 52.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 4.7 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 29.9 thousand years in a starship at a tenth of light speed.
  • Distance. 2985 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 5970 years round-trip.

Standing on it

  • A year here. A full year lasts just 9.9 Earth days.

By the numbers

  • Size. About 1.5× the width of Earth.
  • Mass. About 2.9× the mass of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Temperature. Around 565°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 5 planets orbiting its star.

About Kepler-154 f

Kepler-154 f is an epic exoplanet. It lies about 2,985 light-years from Earth, has an equilibrium temperature near 838 K, spans roughly 1.5 Earth radii and weighs about 2.86 Earth masses.

Crammed into a system of five or more planets.

How to see it

Like any astronomical target, Kepler-154 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-154 f is an epic exoplanet

Kepler-154 f scores 46 points on Spacedle's rarity scale, which places it in the epic tier. Another 22 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Super-Earth, 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.
