The planet which is the closest to every other planet in the solar system; stars escaping their galaxy; the Martian moon that’s one third empty space; and the unidentified anomaly pulling a hundred thousand galaxies (including our own) around.

Mercury is, on average, the nearest planet to Earth. It’s also the nearest planet to every other planet in our solar system.


Runaway stars have been knocked out of their galaxy by black holes or epic galactic collisions.


Phobos, in orbit around Mars, is a rubble moon. It is up to one third empty space inside.
