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.

Look to the sky Friday night for the rare chance to see seven planets lined up. The big picture: Saturn, Mercury, Neptune, Venus, Uranus, Jupiter and Mars will appear together in a "planetary alignment" or "parade of planets" shortly after sunset Friday,

This phenomenon known as a "planet parade," will feature Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune all present at the same time along a line in the night sky on Friday, NASA says.

This week, seven planets will align in what is known as a planetary parade. This planetary parade will see Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn lining up in the evening sky. Four will probably be visible to the naked eye just after sunset.
