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. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 238.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1526 years in a starship at a tenth of light speed.
Distance. 153 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1873.

Saying hello

Say hello. A radio message and its reply would take 305 years round-trip.

Standing on it

A year here. A full year lasts about 7.4 Earth years.

By the numbers

Size. About 13.1× the width of Earth.
Volume. About 2248 Earths could fit inside it.
Mass. Roughly 1014× Earth's mass — about 3.2 Jupiters.
Your weight. You'd weigh about 5.9× your Earth weight standing here.
Temperature. A frigid -146°C — colder than dry ice.

How we found it

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

Cosmic context

Crowded system. One of at least 2 planets orbiting its star.

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

How to see it

Like any astronomical target, HD 37605 c 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 HD 37605 c is a common exoplanet

HD 37605 c scores 23 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Frozen world and Multi-planet system — 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.
