After Friday's spectacle, a "planet parade" of this size won't appear in the night sky for several years, experts say.

Lineups of four or five planets occur every few years, according to NASA. In late August 2025, four planets will be visible before sunrise, and in late October 2028, five planets will be visible at once before sunrise. Another five-planet alignment will occur in late February 2034, with the planets visible after sunset.

Space.com said that Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune will align across the sky just after dusk.
