The 18-year-old Dutchman Oliver Daemen will join Jeff Bezos, the richest person on earth, on a commercial flight to space next week.
It is the first manned flight of the Bezos space company, Blue Origin, which announced the name of Daemen on Thursday.
When the craft leaves the atmosphere, Daemen will be the youngest astronaut ever.
He is also the fourth born Dutchman to ever have been in space, after Lodewijk van den Berg, Wubbo Ockels and André Kuipers.
The launch is scheduled for next Tuesday. The rocket with Daemen, Bezos and two others will reach an altitude of about 100 kilometers after launch. There they see the stars, the edge of the atmosphere and the curvature of the earth, after which they return to the earth's surface.
