"A parade of planets, also sometimes referred to as a planetary alignment, is when several planets in our solar system appear to line up in the sky from our perspective here on Earth," John Conafay, CEO of Integrate Space, tells TODAY.com.

Six of our cosmic neighbors are expected to line up across the night sky tonight, in what has been dubbed a "planetary parade". Throughout much of January and February, Venus, Mars, Jupiter, Saturn, Uranus and Neptune will be visible splayed out in a long arc across the heavens, with Venus, Mars, Jupiter and Saturn being visible to the naked eye.
