Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.
Heavyweight. Packed denser than solid iron.

Could we get there?

Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

Aboard Voyager 1. ≈ 19.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.8 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 11.3 thousand years in a starship at a tenth of light speed.
Distance. 1129 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 897.

Saying hello

Say hello. A radio message and its reply would take 2258 years round-trip.

Standing on it

A year here. A full year lasts just 5.4 Earth days.

By the numbers

Size. About 9.1× the width of Earth.
Volume. About 754 Earths could fit inside it.
Mass. Roughly 8899× Earth's mass — about 28 Jupiters.
Your weight. You'd weigh about 107.4× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 1096°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-5422 b

TOI-5422 b is an epic exoplanet. It lies about 1,129 light-years from Earth, has an equilibrium temperature near 1,369 K, spans roughly 9.1 Earth radii and weighs about 8,899.2 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, TOI-5422 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-5422 b is an epic exoplanet

TOI-5422 b scores 65 points on Spacedle's rarity scale, which places it in the epic tier. Another 3 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Denser than iron, Found by TESS and Distant (>1000 ly) — 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.
