Question

How does an astronaut mass while in orbiting in space while throwing a container in space?

Answer 1

The astronaut's mass is less when he is in orbit. 

Answer 2

In space there are no forces acting, except the forces of celestial bodies, and as there is absence of gravitational pool in space, so any object in space or any astronaut, shall have negligible weight, according to question.

• Our planet earth is also present in space, which orbits in coordination with other planets present in our solar system, around the sun.

• The satellites launched by mankind are rotating round the earth, just for the force acting from celestial bodies, like sun moon earth etc.
