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. ≈ 229.3 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 20.4 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 130.5 thousand years in a starship at a tenth of light speed.
Distance. 13 thousand light-years from Earth.

Look-back time

Look-back time. This light set out before Homo sapiens existed.

Saying hello

Say hello. A radio message and its reply would take 26.1 thousand years round-trip.

By the numbers

Size. About 14.3× the width of Earth.
Volume. About 2924 Earths could fit inside it.
Mass. Roughly 144× 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 OGLE using the microlensing method.

So low-density it would float on water.

How to see it

Like any astronomical target, OGLE-2006-BLG-284L A 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 OGLE-2006-BLG-284L A b is a rare exoplanet

OGLE-2006-BLG-284L A b scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 3 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Puffy low-density world, Found by microlensing 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.
