Why is mercury usually hard to see without a telescope?

Answered by JohnoftheJungle

To see Mercury with your naked eye is only possible when it is at its greatest "elongation" or basically when the angle of separation between the Sun or Mercury is at it's greatest value, however it is not always a promised success of viewing Mercury. It also depends on the phase of the plant to determine how bright it is!
