# At what fraction of the speed of light have people traveled?

I'm guessing that, this would be someone in a rocket or something... When they hit their top speed, at what fraction of $c$ are they traveling?

lurscher's answer is absolutely correct... if you don't specify what the speed is relative to, the answer is any fraction you like. –  AdamRedwine Oct 12 '11 at 20:01
Speed of Earth around Sun is velocity=107,300 km/h ? Don't we all travel at this speed ? Does this count ? –  Andrei Oct 14 '11 at 21:13
@Andrei, no. Doesn't count. –  Abe Miessler Oct 14 '11 at 21:20

Maximum velocity attained by the Apollo spacecraft was 39,897 km/h which is $3.6\times 10^{-5}$ times the speed of light...
When swinging my comfy hammock, I travel all day even up to 0.99 $c$, some days even more, depending on what particles are passing me by and measuring my exorbitant speeds with their atomic clocks and photons..!
