AP: First detection of extra-solar terrestial sized planet?

Escape velocity from Earth for any manned mission
is 11.186 kilometers per second.Minimum.
Go slower than that and you will fall back to Earth.
So the Apollo missions traveled at 64% of the Speed of the Voyager 1 today.
The distance Voyager 1 travels in 80,000
years would take a manned Apollo spacecraft 123,726 years.
The fastest ever manned spacecraft, (Apollo 13 as it plunged back into the earths atmosphere), was doing a lot more than escape velocity.

(or whatever number it is) whatever happened calling things names?
Who gets to decide?
I'd be pretty boring if all our modern day discoveries were just numbers.

Presumably it travelled faster at take off to reach escape velocity. And presumably the Times refer to a sustained velocity.
Apollo 13 clearly finished its journey doing precisely 0 mph.

Brilliant! It was only a matter of time before they could detect the Earth sized planets. Far sooner than I thought they would actually. 'C' huh? Uhh OK

Reminds me of the 1999 movie "Armageddon" when the hick hillbilly astronomer discovers the asteroid that would eventually be the mother of all asteroids. This is when he gets his discovery confirmed and he is on the phone (presumably with someone at the Minor Planet Centre? )
Hick: "The guy who finds it gets to name it, right?"
MPC: "Uh... yeah."
Hick: "I'd like to name it after my wife, Vera." (She looks at him with happy astonishment.) "....She's an evil, life-destroying bitch from whom there is no escape!"
Classic! :lol:
