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. ≈ 3.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 337.8 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2163 years in a starship at a tenth of light speed.
Distance. 216 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1810.

Saying hello

Say hello. A radio message and its reply would take 433 years round-trip.

Standing on it

A year here. A full year lasts about 84.9 Earth years.

By the numbers

Size. About 12× the width of Earth.
Volume. About 1728 Earths could fit inside it.
Mass. Roughly 7501× Earth's mass — about 23.6 Jupiters.
Your weight. You'd weigh about 52.1× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -182°C — colder than dry ice.

How we found it

Discovery. Found by Multiple Observatories using the imaging method.

About HIP 39017 b

HIP 39017 b is an anomaly exoplanet. It lies about 216.3 light-years from Earth, has an equilibrium temperature near 91 K, spans roughly 12 Earth radii and weighs about 7,500.75 Earth masses.

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

How to see it

Like any astronomical target, HIP 39017 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 39017 b is an anomaly exoplanet

HIP 39017 b scores 70 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 25 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, Eccentric orbit, 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.
