# Visibility of Apollo 11 module

I wasn't around when man landed on the moon in 1969. When I see the moon, I always wonder, were people able to see the rocket?

Yesterday, I looked at the moon in daylight and wondered again.

My question is: how far were people able to see the rocket after it launched?

• I think you have an order-of-magnitude error somewhere - I get $\arctan{10m\over 380000km} \approx 10^{-6} \deg$ which is over ten thousand times smaller than the maximum acuity of a human eye with a "perfect" vision. – JohannesD Aug 3 '14 at 16:46
