Guest, it's time once again for the massively important and exciting FoH Asshat Tournament!

Someone mind telling me how we can look at galaxies extremely far away but not know about possible planets orbiting our own? Is it because they don't pass in front of their orbiting star (from our prospective) and thus we have to actually "see" them instead of relying on temps / colors / UV / whatever the hell they usually use?

A galaxy is a lot bigger than a planet.
There are two main methods that I am aware of for detecting exoplanets. They both require prolonged observation. The primary is to find a wobbly star. Through the magic of math and fine observation we can deduce the fact of orbiting mass. Then when we've done that we can turn a telescopic array for an even finer look and confirmation.
And this is the second method, detecting a transit. But that is a matter of resources, patience, and pure blind luck (that's why you look for wobbles first).
The main part of astronomy, besides math, is knowing exactly where to look and exactly when to look. And even then you need to be lucky enough that what you are looking for is both visible and visible from your vantage.

tl;dr we cant use the same methods used to find extra solar planets as planets within our own system.

As was explained to your dumb ass before, when it's all said and done it won't be dozens. It will be hundreds of objects like Pluto:List of possible dwarf planets - Wikipedia, the free encyclopedia
A line had to be drawn somewhere. It made far more sense to draw that line between Neptune and Pluto, than somewhere else further down the line. No definition is perfect.
No, the debate was basically settled. Even if two large planets are found way the fuck out there, the classification (if not the actual name) will still fit them. Because they haven't cleared their orbits.Iannis_sl said:
Basically, the planets that are being talked about here are incredibly faint because they're so far from the Sun. They're also on absolutely massive orbits, and don't tend to move quickly in the sky. The only way to detect them is to do surveys of the sky and look for incredibly faint objects moving faster than the background stars. Even Pluto's original discovery was largely a fluke. Now that they're doing extensive surveys, they're finding dozens of large objects way the fuck out there. See link above.Wuyley_sl said:

Quick, get on the bat phone to the IAU! They never thought of that!

yeah and that shows the error in their thought process. Why is australia a continent but greenland isnt?

Pretty sure you aren't being serious, but Australia is much larger than Greenland. Don't let those silly maps deceive you.

oh good lord I hope you kid. Don't make yourself look pants on head retarded. How about you look up plate tectonics then look up the history of the term continent then slink away slowly.Are YOU being serious?

I'm not really sure what happened there. My point was more reinforcing that no matter how you look at it, geologically or by convention, Australia is a continent and Greenland isn't. I guess I was supposed to be replying to Little Penix and not you? I dunno.
