Trivia

What makes it special

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

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 2.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 255.5 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1636 years in a starship at a tenth of light speed.
Distance. 164 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1862.

Saying hello

Say hello. A radio message and its reply would take 327 years round-trip.

Standing on it

A year here. A full year lasts about 71.5 Earth years.

By the numbers

Size. About 12.6× the width of Earth.
Volume. About 2000 Earths could fit inside it.
Mass. Roughly 2590× Earth's mass — about 8.1 Jupiters.
Your weight. You'd weigh about 16.3× your Earth weight standing here.
Temperature. A frigid -224°C — colder than dry ice.

How we found it

Discovery. Found by Multiple Observatories using the radial velocity method.

About HIP 35965 b

HIP 35965 b is an uncommon exoplanet. It lies about 163.6 light-years from Earth, has an equilibrium temperature near 49 K, spans roughly 12.6 Earth radii and weighs about 2,589.98 Earth masses.

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

How to see it

Like any astronomical target, HIP 35965 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 35965 b is an uncommon exoplanet

HIP 35965 b scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Frozen world and Long-period world — 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.
