Trivia

What makes it special

Frozen world. A deep-frozen world far from its star's warmth.
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. ≈ 2.3 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 204.1 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1307 years in a starship at a tenth of light speed.
Distance. 131 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1895.

Saying hello

Say hello. A radio message and its reply would take 261 years round-trip.

Standing on it

A year here. A full year lasts about 50.9 Earth years.

By the numbers

Size. About 12.2× the width of Earth.
Volume. About 1816 Earths could fit inside it.
Mass. Roughly 5403× Earth's mass — about 17 Jupiters.
Your weight. You'd weigh about 36.3× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -138°C — colder than dry ice.

How we found it

Discovery. Found by Multiple Observatories using the imaging method.

About HIP 99770 b

HIP 99770 b is an epic exoplanet. It lies about 130.7 light-years from Earth, has an equilibrium temperature near 135 K, spans roughly 12.2 Earth radii and weighs about 5,403.08 Earth masses.

A deep-frozen world far from its star's warmth.

How to see it

Like any astronomical target, HIP 99770 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 99770 b is an epic exoplanet

HIP 99770 b scores 61 points on Spacedle's rarity scale, which places it in the epic tier. Another 7 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, Denser than iron 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.
