Whine: is this going to be like Pluto, not a planet, then a planet, now not a planet again? Do you know what a mess my astrological charts are??!!?
Small planets -- a bit of a stretch ? Easier to say than "trans-Neptunian objects"
The great thing about science: discovery and knowledge never end. Only in religion does surprise and new discovery go to die!
It's getting crowded in here, or out there ... I'm still confused about the true nature of space.
so am I
It's big.
@AstralSmoke Thanks for the clarification ...
It is so far between objects out there that one would not have to worry about hitting anything by just pointing in a direction and venturing in that direction. It would be kind of like worrying about hitting something on the highway when the closest object is thousands on miles away on Earth. When plotting trips to Jupiter and beyond we do not worry about hitting anything in the asteroid belt and it is full of stuff, supposedly.
