Trivia

What makes it special

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

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 30.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 2.7 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 17.4 thousand years in a starship at a tenth of light speed.
Distance. 1745 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 281.

Saying hello

Say hello. A radio message and its reply would take 3489 years round-trip.

Standing on it

A year here. A full year lasts just 3.3 Earth days.

By the numbers

Size. About 10.9× the width of Earth.
Volume. About 1281 Earths could fit inside it.
Mass. Roughly 167× Earth's mass — about 0.5 Jupiters.
Your weight. You'd weigh about 1.4× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 1134°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by HATSouth using the transit method.

About HATS-10 b

HATS-10 b is an epic exoplanet. It lies about 1,744.6 light-years from Earth, has an equilibrium temperature near 1,407 K, spans roughly 10.86 Earth radii and weighs about 167.18 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, HATS-10 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 HATS-10 b is an epic exoplanet

HATS-10 b scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Eccentric orbit 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.
