Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 6.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 579.7 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 3712 years in a starship at a tenth of light speed.
- Distance. 371 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1655.
Saying hello
- Say hello. A radio message and its reply would take 742 years round-trip.
Standing on it
- A year here. A full year lasts about 7.9 Earth years.
By the numbers
- Size. About 10.4× the width of Earth.
- Volume. About 1125 Earths could fit inside it.
- Mass. Roughly 4990× Earth's mass — about 15.7 Jupiters.
- Your weight. You'd weigh about 46.1× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A frigid -104°C — colder than dry ice.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit timing variations method.
Cosmic context
- Crowded system. One of at least 3 planets orbiting its star.

How to see it
Like any astronomical target, TOI-201 c 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 TOI-201 c is an epic exoplanet
TOI-201 c scores 46 points on Spacedle's rarity scale, which places it in the epic tier. Another 22 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Eccentric orbit, Denser than iron, Multi-planet system and Found by TESS — 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.
