If you cant prove that the source is unreliable joe, then simply shut up and dont comment on the matter. 
Prove that the source is reliable before talking smack.
I've seen a P-38 listed on a BOEING.GOV or some such website listed at 20,000 feet per second climb.
Point being, you're an idiot. Go do some actual research.
You use some ASTRONOMY.COM as if it were a 100% factual source.
Why not try looking for a GSUIT.ORG instead?
Oh, nevermind. I forget, you're completely oblivious to facts. Keep trusting in the stars my friend, I'm
sure it'll get you somewhere, some day... riiight.
