Trivia

What makes it special

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

Could we get there?

Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

Aboard Voyager 1. ≈ 47.6 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 4.2 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 27.1 thousand years in a starship at a tenth of light speed.
Distance. 2710 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 5420 years round-trip.

Standing on it

A year here. A full year lasts just 4.1 Earth days.

By the numbers

Size. About 14.3× the width of Earth.
Volume. About 2924 Earths could fit inside it.
Mass. Roughly 146× Earth's mass — about 0.5 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.

How we found it

Discovery. Found by La Silla Observatory using the radial velocity method.

About NGC 2682 YBP 401 b

NGC 2682 YBP 401 b is an uncommon exoplanet. It lies about 2,709.8 light-years from Earth, spans roughly 14.3 Earth radii, weighs about 146.2 Earth masses and completes an orbit every 4.09 days.

So low-density it would float on water.

How to see it

Like any astronomical target, NGC 2682 YBP 401 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 NGC 2682 YBP 401 b is an uncommon exoplanet

NGC 2682 YBP 401 b scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Puffy low-density world and Distant (>1000 ly) — 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.
