I made this thread just to see what people say. Thought it might make a good debate

Well, I would label Pluto as a planet, but the same people who claim it isn't a planet call Jupiter, Saturn, Uranus and Neptune planets when they are actually failed stars. They are not planets so why should we accept their definition of a planet?

Does Venus spin backwards? Or has it just been flipped upside down?

Although Jupiter is large as planets go, it would need to be about 75 times its current mass to ignite nuclear fusion in its core and become a star. The other planets you mentioned even more so.

This is an interesting point which is why the Peru Explanet Encylopedia is interesting. What is the division between planet vs ocean worlds and the ocean world vs stars. (Neptune in a different orbit is consider an ocean world or gas gaint depending on how far away from its host Star it is. )

Both :D although what causes retrograde and backwards spinning is a fascinating topic as it's Mercury's orbit.

Uranus (pronounced 'yer a nus') rotates on its side.

I grew up with nine planets but Pluto is not a planet because of its size.
Pluto is a Kuiper Belt object (KBO).

If we class Pluto as a planet we must also class similar sized KBOs as planet and this would mean our system has 17 planets and counting.

We weren't talking about Uranus, but thanks for pointing it out to us.🤣
When I was growing up Pluto was Mickey Mouses dog, guess that's all they really taught us back then?
