Now is your chance to see every planet in our solar system. This parade of seven planets, eight if you include Earth, peaks Friday evening. Mars, Jupiter, Venus, Mercury and Saturn are potentially visible to the naked eye, but you’ll need binoculars or a telescope to see Uranus and Neptune. Those with a clear, low look at the western horizon have a chance for the best view. The best time to look is just after 6 p.m. Eastern time.
