Question

Q.N. 24 It was not more than half an
hour before the peddler and the
blacksmith heard the sound of
wheels.​

Answer 1

During the sunrise the sun is set close to the Earth's horizon, and therefore light travels a longer distance through the atmosphere of the Earth.

This is the reason sun appear reddish early in the morning. The astronaut will not observe this phenomenon on the moon's surface, because the moon has no atmosphere.
