Get ready, Mercury will enter its first retrograde period this year from Feb. 26 through March 20.

As the planet of communication appears to move backward in the sky, expect delays or glitches in areas like travel, contracts, conversations and technology.

A planetary retrograde is when a planet appears to be moving backward in the sky from our perspective here on Earth, even though it's traveling straight in its orbit.

"Retrograde" comes from the Latin word "retrogradus," which combines the words "retro," which means "backward," and "gradus," which means "step." The word "anapodizō," which means "to step or go back," was used by the ancient Greeks.
