Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 30.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.7 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 17.3 thousand years in a starship at a tenth of light speed.
  • Distance. 1730 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 296.

Saying hello

  • Say hello. A radio message and its reply would take 3460 years round-trip.

Standing on it

  • A year here. A full year lasts just 4.2 Earth days.

By the numbers

  • Size. About 1.2× the width of Earth.
  • Mass. Roughly 120× Earth's mass — about 0.4 Jupiters.
  • Your weight. You'd weigh about 81.9× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A scorching 421°C on average.

How we found it

  • Discovery. Found by Kepler using the transit timing variations method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.

About Kepler-415 b

Kepler-415 b is an epic exoplanet. It lies about 1,730.2 light-years from Earth, has an equilibrium temperature near 694 K, spans roughly 1.21 Earth radii and weighs about 119.9 Earth masses.

Packed denser than solid iron.

How to see it

Like any astronomical target, Kepler-415 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-415 b is an epic exoplanet

Kepler-415 b scores 58 points on Spacedle's rarity scale, which places it in the epic tier. Another 10 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Earth-sized, Denser than iron, Multi-planet 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.
