Trivia

What makes it special

Cotton-candy planet. So low-density it would float on water.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 4.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 372.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2384 years in a starship at a tenth of light speed.
Distance. 238 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1788.

Saying hello

Say hello. A radio message and its reply would take 477 years round-trip.

Standing on it

A year here. A full year lasts about 3.4 Earth years.

By the numbers

Size. About 12.7× the width of Earth.
Volume. About 2048 Earths could fit inside it.
Mass. Roughly 108× Earth's mass — about 0.3 Jupiters.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. A frigid -64°C — colder than dry ice.

How we found it

Discovery. Found by W. M. Keck Observatory using the radial velocity method.

About HD 126614 b

HD 126614 b is an uncommon exoplanet. It lies about 238.4 light-years from Earth, has an equilibrium temperature near 210 K, spans roughly 12.7 Earth radii and weighs about 107.74 Earth masses.

So low-density it would float on water.

How to see it

Like any astronomical target, HD 126614 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 HD 126614 b is an uncommon exoplanet

HD 126614 b scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Eccentric orbit and Puffy low-density 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.
