We constantly redefine our world based on new information. Things get re-classified. Hell, I am now classified as 'old'! :-)
Is Pluto a planet? Does it qualify? For an object to be a planet, it needs to meet these three requirements defined by the IAU:
- It needs to be in orbit around the Sun – Yes, so maybe Pluto is a planet.
- It needs to have enough gravity to pull itself into a spherical shape – Pluto…check
- It needs to have “cleared the neighborhood” of its orbit – Uh oh. Here’s the rule breaker. According to this, Pluto is not a planet.
...the majority is always wrong, and always the last to know about it...
A solution is nothing more than a clearly stated problem...
