Silly question about orbits
Hi all!
From what I understand from my research on Kerbal Space Program, to increase your orbit around a planet, you have to burn prograde; in other words you have to accelerate in the direction your ship si going.
Now let's say you're an astronaut in EVA, strapped to the "front" of the ISS. Obviously you've brought your potato gun with you, in case such an occasion would arise where a potato gun would be vital.
If you fire your potato gun prograde, while at perigee, you would impart a sudden and brief positive acceleration to the hapless starchy tuberous vegetable in the direction that the ISS is going. My question is : would that increase the orbit of said proto-french-fry at the apogee?
Feel free to discard any trivial factor in answering, such as the mass of the earth or of the potato, or even the inital force propelling the small piece of food forth.
Thank you for reading my shower thought.
