Six planets will be visible in the night sky at the end of February, and most can be seen with the naked eye. It’s what’s known as a planetary parade, which happens when multiple planets appear to line up in the sky at once. On Saturday, go outside about an hour after sunset and venture away from tall buildings and trees. Look to the western sky and spot Mercury, Venus and Saturn close to the horizon. Jupiter will be higher up, along with Uranus and Neptune, but those last two are only visible with binoculars and telescopes.
