It was a burning question of mine for a while now:
I understand that dwarf planets like Pluto and Ceres aren’t considered planets of the solar system, but why are they called ‘dwarf PLANETS’ if they aren’t planets.
And no one really says, “the sun isn’t a star, it’s a Dwarf Star”. Nor is it declassified as one because of it.
So, why are dwarf planets not planets, but dwarf stars are stars?
It’s basically it’s large enough to be round like a planet but can’t achieve orbital dominance like the big 8. So it looks like a planet but acts like an astroid. I think dwarf planet is a good term for them. Becase if they were a little bigger they would have all the same properties of a planet and are a lot closer to becoming a planet that than an asteroid.
Hell I think Jupiter shouldn’t be a planet. Since it’s really close to being a star. I think it should be classified as a protostar.
How much bigger would Jupiter have to be before fusion started?
Just the extra mass of 13 times I know doesn’t sounds like a lot but going from Earth to Jupiter’s is about 318 times. Maybe instead of protostar we should use failed star since it has all the hydrogen and seller dust of that a star would used forces fuel.
