Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 9.1 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 811 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 5194 years in a starship at a tenth of light speed.
Distance. 519 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1507.

Saying hello

Say hello. A radio message and its reply would take 1039 years round-trip.

Standing on it

A year here. A full year lasts just 8.8 Earth days.

By the numbers

Size. About 10.7× the width of Earth.
Volume. About 1238 Earths could fit inside it.
Mass. Roughly 80.8× Earth's mass — about 0.3 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 581°C — hotter than a self-cleaning oven.

How we found it

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

About 10.7× the width of Earth.

How to see it

Like any astronomical target, IRAS 04125+2902 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 IRAS 04125+2902 b is a trash exoplanet

IRAS 04125+2902 b scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant 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.
