Space is so big that even asteroid belts are relatively empty. The possibility of hitting a space rock is so remote, scientists barely consider it.

Speed and gravity directly affect how an object experiences time. The faster you go, the slower time will pass for you compared to slower objects. Taking this into account, satellites orbiting Earth have their clocks set at a deliberately slower pace than clocks on Earth.
