Trivia

What makes it special

Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.
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. ≈ 3.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 345.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2212 years in a starship at a tenth of light speed.
Distance. 221 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1805.

Saying hello

Say hello. A radio message and its reply would take 442 years round-trip.

Standing on it

A year here. A full year lasts about 4.1 Earth years.

By the numbers

Size. About 12.5× the width of Earth.
Volume. About 1953 Earths could fit inside it.
Mass. Roughly 3117× Earth's mass — about 9.8 Jupiters.
Your weight. You'd weigh about 20.0× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -26°C — colder than dry ice.

How we found it

Discovery. Found by Lick Observatory using the radial velocity method.

Cosmic context

Wild orbit. Its highly elliptical path swings between scorching and frozen each lap.

About HD 86264 b

HD 86264 b is an epic exoplanet. It lies about 221.2 light-years from Earth, has an equilibrium temperature near 247 K, spans roughly 12.5 Earth radii and weighs about 3,117.26 Earth masses.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, HD 86264 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 HD 86264 b is an epic exoplanet

HD 86264 b scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 2 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Gas giant, Eccentric orbit 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.
