You are a complete idiot/troll
1) Pluto was discovered LONG before 1983, venus was "discovered" by some pre human ape that happened to look up... (I believe ir was Dr. Eeegah of the Institute of feces throwing)
2) Orion is a constellation
3) PX claims are bullshit unless they are supported by hard data other than BS you unthinkingly read on the internet....
4) Get a f'ing brain
5) quit trolling here
6) for gods sake please do not vote until you learn how to think!!!!
