Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 39.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 3.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 22.6 thousand years in a starship at a tenth of light speed.
  • Distance. 2257 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 4515 years round-trip.

Standing on it

  • A year here. A full year lasts just 150 Earth days.

By the numbers

  • Size. About 32.6× the width of Earth.
  • Volume. About 34.6 thousand Earths could fit inside it.
  • Temperature. A scorching 52°C on average.

How we found it

  • Discovery. Found by Kepler using the transit method.

Cosmic context

  • Crowded system. One of at least 3 planets orbiting its star.

About Kepler-297 d

Kepler-297 d is an uncommon exoplanet. It lies about 2,257.5 light-years from Earth, has an equilibrium temperature near 325 K, spans roughly 32.6 Earth radii and completes an orbit every 150.02 days.

One of at least 3 planets orbiting its star.

How to see it

Like any astronomical target, Kepler-297 d 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-297 d is an uncommon exoplanet

Kepler-297 d scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, 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.
