A six-planet parade — sometimes called a planetary alignment — will adorn the pre-sunrise morning sky on Friday, Aug. 22, with four of them visible to the naked eye. Venus, Jupiter and Saturn will be easy to see, while tiny Mercury is visible this week shortly before sunrise. Uranus and Neptune are also in the night sky, but can only be seen using binoculars or a telescope. Mercury will have sunk by next week, effectively reducing the sight to a five-planet parade.
