7 planets are aligning in the night sky for a "planetary parade." Here's what to know.

Seven planets are aligning in the night sky this week, creating a brief chance to see a "planetary parade."

Mercury, Venus, Mars, Jupiter, Saturn, Neptune and Uranus could all be visible with clear skies, but not all can be seen by the naked eye, according to Space.com and other sites that track celestial events.

For the best chances, spectators should look at the sky as soon as the sun sets. That's when the planets will make a brief appearance.
