What changed our view of Chariklo is the discovery of a ring system around it, the first such feature found around a Solar System body smaller than a gas giant planet. ... Almost certainly the rings were born when a collision with a smaller asteroid blasted millions of tonnes of debris off CharikloтАЩs surface. ...

... A rogue planet has been spotted wandering alone through space with no parent star in sight! ... It's even harder when the object is very dark and floating through space. ... These are star-like objects that are much bigger than planets up to about 80 times bigger than Jupiter but too small to be stars. ... Cool Fact: Some astronomers say there are about twice as many rogue planets as there are stars in our galaxy; other think there are up to 100,000 times more! ...

... Indeed, one alteration of orbits can be the outright ejection of a planet. When several big planets are orbiting a star under each other's influence, the system is inherently unstable. ... We know of no good reason why the smallest objects with fusion should have the same mass as the smallest objects that can form by themselves. ... 6) Mission Definition . ... I don't think this mission is impossible, and will suggest a definition in a future article in Mercury. ... Good luck! . ...
