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.

Luna skims by Mercury, Venus, Uranus, Neptune, and Jupiter as it grows from a thin crescent to just past First Quarter in the sky this week.

Commonly called a planetary parade or alignment, this event happens when several planets appear close together in the sky from Earth's perspective. This grouping occurs when all the planets travel around the Sun along a nearly flat plane called the ecliptic,

According to NASA, multi-planet lineups are visible "every few years," but a seven-planet alignment is particularly uncommon, as each planet's orbit varies, with some moving more quickly and Mercury, in particular, being visible during its 88-day orbit for only "a couple of weeks at a time" each year.

A stunning photo of a "parade of planets", shows Mars, Jupiter, Uranus, Saturn, Venus, Neptune, and Mercury in alignment from Earth. The image could be the first of its kind.

The planets are set to align tonight when Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn form a parade which will be visible from Derry and Donegal.
