Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 19.6 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.7 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 11.2 thousand years in a starship at a tenth of light speed.
Distance. 1117 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 909.

Saying hello

Say hello. A radio message and its reply would take 2235 years round-trip.

Standing on it

A year here. A full year lasts just 83 Earth days.

By the numbers

Size. About 11.1× the width of Earth.
Volume. About 1366 Earths could fit inside it.
Mass. Roughly 1197× Earth's mass — about 3.8 Jupiters.
Your weight. You'd weigh about 9.7× your Earth weight standing here.
Temperature. A frigid -90°C — colder than dry ice.

How we found it

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

Cosmic context

Crowded system. One of at least 3 planets orbiting its star.

About TOI-4504 c

TOI-4504 c is an uncommon exoplanet. It lies about 1,117.4 light-years from Earth, has an equilibrium temperature near 183 K, spans roughly 11.1 Earth radii and weighs about 1,197.32 Earth masses.

One of at least 3 planets orbiting its star.

How to see it

Like any astronomical target, TOI-4504 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-4504 c is an uncommon exoplanet

TOI-4504 c scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Multi-planet system, 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.
