Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.
Cotton-candy planet. So low-density it would float on water.

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 16.4 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.5 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 9325 years in a starship at a tenth of light speed.
Distance. 932 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1094.

Saying hello

Say hello. A radio message and its reply would take 1865 years round-trip.

Standing on it

A year here. A full year lasts just 3.7 Earth days.

By the numbers

Size. About 15.6× the width of Earth.
Volume. About 3766 Earths could fit inside it.
Mass. Roughly 176× Earth's mass — about 0.6 Jupiters.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 1343°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

About TOI-3321 b

TOI-3321 b is an epic exoplanet. It lies about 932.5 light-years from Earth, has an equilibrium temperature near 1,616 K, spans roughly 15.56 Earth radii and weighs about 176.08 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, TOI-3321 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 TOI-3321 b is an epic exoplanet

TOI-3321 b scores 49 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Puffy low-density world 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.
