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. ≈ 8.1 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 721.1 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4618 years in a starship at a tenth of light speed.
Distance. 462 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1564.

Saying hello

Say hello. A radio message and its reply would take 924 years round-trip.

By the numbers

Size. About 16.3× the width of Earth.
Volume. About 4293 Earths could fit inside it.
Mass. Roughly 3178× Earth's mass — about 10 Jupiters.
Your weight. You'd weigh about 12.0× your Earth weight standing here.
Temperature. Around 1312°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Paranal Observatory using the imaging method.

Why HD 135344 A b is an epic exoplanet

HD 135344 A 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.
