Hello, I have been doing extensive research into planetary positions and distances from the sun. When viewing the sky for planets it has been noticed that Mercury is in the night sky. Mercury is at 36million miles from the Sun. Earth is 93million miles from the Sun. How can the planet Mercury be seen at night when it is orbiting the Sun much tighter to it then Earth? Based on drawing diagrams to replicate what I can see I can not find an angle that shows Mercury visible at night. What am I doing wrong?
