We instinctively think of planets as rocky or gaseous bodies orbiting a star like our sun, with sunrise, sunset, heating and maybe even seasons. But what if a planet didn't orbit a light source? What if it just floated through space vaguely orbiting the centre of the galaxy, but tugged this way and that way by nearby stars and stellar systems. These are rogue planets. No sunrise, no sunset, no heat from an outside source. Just starlight and blackness as it wandered aimlessly through lonely interstellar space. And they just might be the most common type of planet in our galaxy.
