Find mistake (flagged)


Find the mistake and correct it.


The space station orbits an earth and a rocket refuels it as it orbits.


For my opinion, I see that this sentence may has two mistakes that are (an earth=the earth or as it orbits = as it spins) but I'm not sure. so I need your help.

Yes, it should be the earth.


No, do not change orbits to spins.  These words mean two different things.  A space station orbits the earth.  If it was also spinning, the astronauts would be very dizzy.  The earth does both - it orbits the sun and spins on its axis.  Do you see the difference?
