Trivia

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 14.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.3 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 8480 years in a starship at a tenth of light speed.
  • Distance. 848 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1178.

Saying hello

  • Say hello. A radio message and its reply would take 1696 years round-trip.

Standing on it

  • A year here. A full year lasts just 7.4 Earth days.

By the numbers

  • Size. Around 74% of Earth's width.
  • Mass. About 0.5× the mass of Earth.
  • Your weight. You'd weigh about 0.9× your Earth weight standing here.
  • Temperature. A scorching 349°C on average.

How we found it

  • Discovery. Found by Kepler using the transit method.

Cosmic context

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

About Kepler-345 b

Kepler-345 b is a trash exoplanet. It lies about 848 light-years from Earth, has an equilibrium temperature near 622 K, spans roughly 0.74 Earth radii and weighs about 0.48 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, Kepler-345 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-345 b is a trash exoplanet

Kepler-345 b scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Multi-planet system and Found by Kepler — 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.
