On Feb. 28, seven planets—Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn—will all grace the early evening sky. Mercury, Venus, Jupiter, and Mars will be easy to spot with the naked eye, while Uranus and Neptune will require binoculars or a small telescope.

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.

After dusk on Friday night, seven planets are expected to align in the night sky. But you'll need binoculars or a telescope to see them all.

Beginning around sunset, Saturn will be situated closest to the horizon, followed by Mercury, Venus, Jupiter and Mars higher in the sky. While Neptune and Uranus also are within Earth’s line of sight, they’ll require binoculars or a telescope and are extremely difficult to locate, astronomers say.

Houstonians will be able to see seven planets in the sky this weekend in what's called a planetary parade. Unfortunately, however, some may not be spotted with the naked eye. Just after dark, it will be possible to view Mercury,

Friday is the last day where the rare phenomenon known as a 'planetary parade' is visible in the sky, although clouds have obscured the view in some areas. Join Dr Robert Massey, Dr Sheila Kanani, and Prof Catherine Heymans,
