Well, I don't know about you guys but I was rather disappointed and upset at the demotion of Pluto's status as a planet.

What is your thoughts on this?

I love the idea of it being a planet. Besides, can someone explain to me what they think constitutes a planet?

I think the other planets are referred to as planets, because they were formed around the sun (like Earth). Many think that Pluto was a captured object (asteroid), which wasn't formed around the sun like the others.
However, Pluto does have a moon (like all the other planets except Mercury and Venus), so I was thinking "Why bother to demote it - what difference does it make?"
They reckon there are even more "object" orbiting the sun in a similar way to pluto, and that they were also captured.
To summerise, I am quite happy for it to be a planet, because it has its own moon - albeit, a captured planet.

Yeah, I still think of Pluto as a planet.

This is what Wikipaedia has to say about planets

The International Astronomical Union (IAU) defines "planet" as a celestial body that, within the Solar System,

(a ) is in orbit around the Sun;
(B ) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; and
(c ) has cleared the neighbourhood around its orbit;


I suppose I can see why one would say that Pluto is not a regular planet, because it's orbit around the Sun is not a circle like the other planets - for much of the time it is inside the orbit of neptune, and other times, it is outside. Also, its orbital path is not on quite the same plane as the other planets (i.e. sometimes it is above the orbital plane of other planets, and other times below.

I still think of it as a planet, because it has its own moon, and it fits all the above requirements for a planet. I think they are classing it as a "proto-planet", much like Ceres (Ceres is a very large "asteroid" orbiting within the asteroid belt, but it is so big for an asteroid it is classed as a "proto-plant" or micro-planet.)

Yeah, I heard about that... don't worry about remaining on topic...

It was crazy sometimes truth is stranger than fiction, huh?

Pluto's A Planet!

I stand by that whatever these dumb scientists says!
