"If it takes 18 seconds for Light to reach Earth from the Sun, then the Earth would be orbiting where the Sun was 18 seconds ago if Gravity travels at the speed of Light, with an even more pronounced lag in horizontal plane orbit for Mars, Saturn, etc."

Every word in your posting is wrong, including "is", "and" and "the".

You cannot even give the correct distance to the Sun in light-seconds. The Sun is about 8.3 light minutes from Earth.

"The Sun is about 8.3 light minutes from Earth."

Relative to its former position, how far will the Sun have moved in 8.3 minutes?
