You only detect the object when it is 1.2 light minutes away because of the resolution of your telescope. But by the time that light reaches you, the object is only 0.72 light seconds behind the light. There is no "head-start", because the object is moving (from the perspective of the pilot) while the light is traveling. | |

| Mar 11, 2018 at 13:40 | comment | added | fishinear | @NPSF3000 A "1.2-minute headstart" would mean that the light leaves the object 1.2 minutes before the object starts moving. That is not the case, it is already moving. And so the object arrives at you only 0.73 seconds after its light does. | |

Without having checked your calculations, I suspect that you at the very least got these numbers the wrong way around. | |
