    What if a planet that is Earth-sized falls down on Earth from let’s say 5-10 meters though?

      A thing that size would have initial velocity to begin with,

      But acceleration does not depend on mass, (which is kinda weird from an earthling’s perspective), which Einstein formalized in an amazingly powerful theory called General Relativity

      It would fall at 2g, because two Earth-sized masses attract each other in that case. With smaller objects it’s just 1g, because the mass of, let’s say, a nice cup of tea is negligible compared to the mass of Earth.
