Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 6.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 554.5 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 3551 years in a starship at a tenth of light speed.
Distance. 355 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1671.

Saying hello

Say hello. A radio message and its reply would take 710 years round-trip.

By the numbers

Size. About 16.8× the width of Earth.
Volume. About 4753 Earths could fit inside it.
Mass. Roughly 2860× Earth's mass — about 9 Jupiters.
Your weight. You'd weigh about 10.1× your Earth weight standing here.
Temperature. Around 1227°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Paranal Observatory using the imaging method.

About HIP 65426 b

HIP 65426 b is an epic exoplanet. It lies about 355.1 light-years from Earth, has an equilibrium temperature near 1,500 K, spans roughly 16.81 Earth radii and weighs about 2,860.47 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, HIP 65426 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 HIP 65426 b is an epic exoplanet

HIP 65426 b scores 49 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world and Directly imaged — 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.
