Mercury

The moon will meet up with Mercury, the solar system's smallest planet and the closest to the sun, in the evening sky on Wednesday, May 17.

Shortly after Mercury reached its closest point to the sun, its massive, comet-like tail became unusually visible in the night sky and was captured in a stunning new photo.

Mercury will reach its highest point in the sky tonight (April 11), but it'll still be a challenge to observe.
