[QUOTE="Simon Bridge, post: 4520810, member: 367532"] Depends on the relative speed of the planet doesn't it. Can you assume the Earth and Exoplaten clocks share a reference frame? In her reference frame, the Earth and the planet are moving at 0.999c, and their distance is contracted. You should draw the space-time diagrams for each reference frame to compare them.
