Somebody made a point in another thread about how textbooks are revamped every year, anyway. It's called "Editions". They update it with more knowledge.
Pluto's orbit is round... all orbits are round I think. I've never heard of a square orbit. Pluto's orbit goes inside of neptunes, though. None of the other planets do that because they have a large enough mass to sustain themselves. Obviously, if it's going inside of neptunes orbit, it doesn't have a perfectly round orbit among other things.... i know orbits are eliptical so halfway ignore my last statement.
All objects have a gravitational pull, it's just the extent to which it pulls that's in question. Should we call every asteroid and moon a planet simply because it has a gravitational pull and a round orbit that goes around a star? lol Think about all the updates to textbooks that would require geggy we'd have to say that every asteroid is now a planet
I sincerely doubt that the new editions of books were printed right away at cost. I'm sure plenty of textbooks will remain unupdated.
What the hell is an "Education dept.". Don't take that literaly, because I know what it is, I just don't understand your usage of the word.
