The most difficult visible planet isn’t the farthest from us, it is almost always the one too close to the sun. The planet Mercury shines above the eastern skyline each morning in the week ahead.
Mercury is tough. But this weekend, Mercury will be easy. Astronomers point out that this is the best apparition of the Sun’s closest planet Mercury.
There are only two requirements for seeing this planet. Get up early in the morning well before sunrise, and the eastern sky has to be clear.
