Trivia

What makes it special

Frozen world. A deep-frozen world far from its star's warmth.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 86.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 7.7 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 49.2 thousand years in a starship at a tenth of light speed.
Distance. 4925 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 9850 years round-trip.

Standing on it

A year here. A full year lasts about 4.9 Earth years.

By the numbers

Size. About 14× the width of Earth.
Volume. About 2744 Earths could fit inside it.
Mass. Roughly 231× Earth's mass — about 0.7 Jupiters.
Your weight. You'd weigh about 1.2× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. A frigid -191°C — colder than dry ice.

How we found it

Discovery. Found by OGLE using the microlensing method.

Cosmic context

Crowded system. One of at least 2 planets orbiting its star.

About OGLE-2006-BLG-109L b

OGLE-2006-BLG-109L b is a rare exoplanet. It lies about 4,925 light-years from Earth, has an equilibrium temperature near 82 K, spans roughly 14 Earth radii and weighs about 231 Earth masses.

A deep-frozen world far from its star's warmth.

How to see it

Like any astronomical target, OGLE-2006-BLG-109L 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-109L b is a rare exoplanet

OGLE-2006-BLG-109L b scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Frozen world, Multi-planet system, 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.
