The longest lunar eclipse of this century comes in two weeks.

During the early hours of November 19, Earth will pass between the sun and moon, casting a shadow over the latter. The eclipse will peak just after 4 a.m. ET, when our planet will hide 97% of the full moon from the sun's light, giving the moon a reddish hue.

According to NASA, the partial lunar eclipse will last 3 hours, 28 minutes, and 23 seconds — longer than any other eclipse between 2001 and 2100.
