"These things exist!"
I learned recently that there is such a thing as a planet without an orbit. Depending on how it was formed, it could be a protostar that never became massive enough to fire up the typical heat- and light-producing reactions, or a castoff from a new star's protoplanetary disc. The first kind are "sub-brown dwarves", the second sometimes called "rogue planets".
I've loved this image for years; this one and "The Brink" (also an early work) just make me 'hear' and 'feel' the silence of things drifting in the aftermath of a wordless creation... And then I found out they're real. Ryan, either you're more smarter than me (not hard to do) or you've made some outrageously good guesses!
