Trivia

What makes it special

Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 160.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 14.3 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 91.3 thousand years in a starship at a tenth of light speed.
Distance. 9132 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 18.3 thousand years round-trip.

By the numbers

Size. About 12.4× the width of Earth.
Volume. About 1907 Earths could fit inside it.
Mass. Roughly 3500× Earth's mass — about 11 Jupiters.
Your weight. You'd weigh about 22.8× your Earth weight standing here.
Density. Denser than solid iron.

How we found it

Discovery. Found by MOA using the microlensing method.

Why MOA-2010-BLG-073L b is an epic exoplanet

MOA-2010-BLG-073L b scores 49 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Denser than iron, 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.
