Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 624 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 55.4 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 355 years in a starship at a tenth of light speed.
- Distance. 35.5 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1990.
Saying hello
- Say hello. A radio message and its reply would take 71 years round-trip.
Standing on it
- A year here. A full year lasts about 1.1 million Earth years.
By the numbers
- Size. About 12.6× the width of Earth.
- Volume. About 1989 Earths could fit inside it.
- Mass. Roughly 2384× Earth's mass — about 7.5 Jupiters.
- Your weight. You'd weigh about 15.1× your Earth weight standing here.
- Temperature. A scorching 220°C on average.
How we found it
- Discovery. Found by NASA Infrared Telescope Facility (IRTF) using the imaging method.

How to see it
Like any astronomical target, COCONUTS-2 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 COCONUTS-2 b is a rare exoplanet
COCONUTS-2 b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Long-period world and Directly imaged — 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.
