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. ≈ 14.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.3 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 8264 years in a starship at a tenth of light speed.
- Distance. 826 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1200.
Saying hello
- Say hello. A radio message and its reply would take 1653 years round-trip.
Standing on it
- A year here. A full year lasts just 69 Earth days.
By the numbers
- Size. About 11.5× the width of Earth.
- Volume. About 1521 Earths could fit inside it.
- Mass. Roughly 4049× Earth's mass — about 12.7 Jupiters.
- Your weight. You'd weigh about 30.6× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A scorching 244°C on average.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

Why TIC 4672985 b is an uncommon exoplanet
TIC 4672985 b scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Denser than iron 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.
