Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 1 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 89.8 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 575 years in a starship at a tenth of light speed.
- Distance. 57.5 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1968.
Saying hello
- Say hello. A radio message and its reply would take 115 years round-trip.
Standing on it
- A year here. A full year lasts just 14.4 Earth days.
By the numbers
- Size. About 3.7× the width of Earth.
- Volume. About 51.1 Earths could fit inside it.
- Mass. About 13.3× the mass of Earth.
- Your weight. You'd weigh about 1.0× your Earth weight standing here.
- Temperature. A scorching 99°C on average.
How we found it
- Discovery. Found by Calar Alto Observatory using the radial velocity method.

Why LSPM J2116+0234 b is a trash exoplanet
LSPM J2116+0234 b scores 10 points on Spacedle's rarity scale, which places it in the trash tier. Another 5 points would lift it into a rarer tier.
That score comes from 2 science badges — Confirmed exoplanet and Sub-Neptune — 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.
