Yuri Gagarin did.
Gagarin made one orbit of the earth in 108 minutes before coming back home.
how far away from the earth did yuri gagarin travel?
Gagarin was the first person to leave the Earth's atmosphere.
He wasn't. Yuri Gagarin orbited the earth - once - in 1961, a year before Glenn's flight.
Gagarin orbited the Earth on April 12, 1961
It took Yuri Gagarin 108 minutes to orbit the Earth.
No human being has ever flown into Orbit before Yuri did. The soviets only flew their sattelites and put them into Earth's orbit. So we can indicate that: Yuri Gagarin is the first human being sent into Space :)
