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. ≈ 225.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 20 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 128.2 thousand years in a starship at a tenth of light speed.
Distance. 12.8 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 25.6 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 3585× Earth's mass — about 11.3 Jupiters.
Your weight. You'd weigh about 23.3× your Earth weight standing here.
Density. Denser than solid iron.

How we found it

Discovery. Found by OGLE using the microlensing method.
