NEW YORK (AP) — Seven planets grace the sky at the end of February in what’s known as a planetary parade, though some will be difficult to spot with the naked eye. These planetary hangouts happen when several planets appear to line up in the night sky at once. They’re not in a straight line, but are close together on one side of the sun.

Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn will all be briefly visible in the evening sky. This phenomenon, known as a 'planetary parade' is a rare sight, and it will be the last time seven planets can be seen simultaneously until 2040.
