Trivia
Standing on it
- A year here. A full year lasts just 2 Earth days.
By the numbers
- Size. About 6.8× the width of Earth.
- Volume. About 316 Earths could fit inside it.
- Mass. About 37.3× the mass of Earth.
- Your weight. You'd weigh about 0.8× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 402°C on average.

Why Kepler-1984 b is a trash exoplanet
Kepler-1984 b scores 12 points on Spacedle's rarity scale, which places it in the trash tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant 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.
