About HD 114386 c
HD 114386 c is an uncommon exoplanet. It lies about 91.1 light-years from Earth, has an equilibrium temperature near 201 K, spans roughly 13.4 Earth radii and weighs about 117.6 Earth masses.
So low-density it would float on water.

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. ≈ 1.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 142.2 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 911 years in a starship at a tenth of light speed.
- Distance. 91.1 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1935.
Saying hello
- Say hello. A radio message and its reply would take 182 years round-trip.
Standing on it
- A year here. A full year lasts just 444 Earth days.
By the numbers
- Size. About 13.4× the width of Earth.
- Volume. About 2406 Earths could fit inside it.
- Mass. Roughly 118× Earth's mass — about 0.4 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 -72°C — colder than dry ice.
How we found it
- Discovery. Found by Las Campanas Observatory using the radial velocity method.
Cosmic context
- Crowded system. One of at least 2 planets orbiting its star.

How to see it
Like any astronomical target, HD 114386 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 114386 c is an uncommon exoplanet
HD 114386 c 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, Puffy low-density 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.
