Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 7.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 684 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4381 years in a starship at a tenth of light speed.
Distance. 438 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1588.

Saying hello

Say hello. A radio message and its reply would take 876 years round-trip.

Standing on it

A year here. A full year lasts just 0.2 Earth days.

By the numbers

Size. Around 61% of Earth's width.
Mass. About 8× the mass of Earth.
Your weight. You'd weigh about 21.5× your Earth weight standing here.
Temperature. Around 1381°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 2 planets orbiting its star.

Why KOI-1843.03 is an epic exoplanet

KOI-1843.03 scores 50 points on Spacedle's rarity scale, which places it in the epic tier. Another 18 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Lava world, Ultra-short period, Multi-planet system, Blasted by starlight 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.
