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. ≈ 1.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 105.8 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 677 years in a starship at a tenth of light speed.
Distance. 67.7 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1958.

Saying hello

Say hello. A radio message and its reply would take 135 years round-trip.

Standing on it

A year here. A full year lasts just 246 Earth days.

By the numbers

Size. About 11.9× the width of Earth.
Volume. About 1685 Earths could fit inside it.
Mass. Roughly 9058× Earth's mass — about 28.5 Jupiters.
Your weight. You'd weigh about 64.0× your Earth weight standing here.
Density. Denser than solid iron.

How we found it

Why DENIS-P J082303.1-491201 b is an uncommon exoplanet

DENIS-P J082303.1-491201 b scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Denser than iron — 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.
