Why is it sometimes difficult to see Mercury in the sky?

Mercury can be challenging to see in the sky because it is the closest planet to the Sun, which means it is often lost in the Sun's glare. Additionally, Mercury has a short orbit, leading to limited viewing Windows during dawn or dusk, when it is most visible. Its small size and lack of bright features also make it less noticeable compared to other planets. Observers typically need to know the right times and positions to successfully spot it.
