About WASP-69 b
WASP-69 b is a common exoplanet. It lies about 162.9 light-years from Earth, has an equilibrium temperature near 971 K, spans roughly 11.21 Earth radii and weighs about 82.58 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. ≈ 2.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 254.4 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1629 years in a starship at a tenth of light speed.
- Distance. 163 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1863.
Saying hello
- Say hello. A radio message and its reply would take 326 years round-trip.
Standing on it
- A year here. A full year lasts just 3.9 Earth days.
By the numbers
- Size. About 11.2× the width of Earth.
- Volume. About 1409 Earths could fit inside it.
- Mass. Roughly 82.6× 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. Around 698°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by SuperWASP using the transit method.

How to see it
Like any astronomical target, WASP-69 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 WASP-69 b is a common exoplanet
WASP-69 b scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant 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.
