because of the gravity of the big planet

your numbers are fubar so I'm gonna explain it with the equation gravitational froce= GmM/(r)^2.

umm the planet looked like it was 3 times the size of the earth so that would be like 900000000000000 kg and like 5000000000 m around. and the ship probably weighed like 50000 kg or something so when you plug it in its someting like 400000 N but I don't like that so I'm gonna make it in english and it's like 5 bajillion Ilbs.

so you can see how the ship could never have penetrated to the center of jedi temples.
