So, is Pluto a planet or not?
The International Astronomical Union applied some rigor to the definition of ‘planet’.
1. Has to have enough gravity to make itself spherical (yes).
2. Has to orbit the sun (yes).
3. Has to have enough mass to clear its orbit of other objects (no)
There are actually bigger ‘dwarf planets’ out there than Pluto. Eris is one of them. Interesting that there was no weight at all as to whether the planetoid in question could hold satellites. Pluto has 5.
They are now called ‘dwarf planets’. Apparently, it is OK to offend planetoids with the pejorative ‘dwarf’. Try that with a ‘little person’.
It’s round, it’s in a stable orbit, it has moons, it, to me, is a planet, just smaller. They can call it a ‘planetoid’ or whatever they wish, but it is a planet..............
