A rare treat is about to appear in Earth’s night sky. On February 28, 2025, all seven planets in our Solar System will align at the same time, a spectacular event known as a great planetary alignment. This alignment occurs when six of the planets are already aligned and a seventh planet joins them.
This alignment is rare because it requires all seven planets to be on the same side of the Sun. However, it’s not uncommon for three to eight planets to align at any given time, with five or six planet alignments being more frequent than six.
The alignment isn’t a physical queue like you’d see in diagrams; instead, the planets appear to line up because they orbit the Sun on a flat plane called the ecliptic. The positions of these planets are influenced by their orbits and the way stars form.
To witness this event, use online tools such as Time and Date’s interactive tool or Stellarium’s web tool to determine viewing times and locations. You’ll also need binoculars or a telescope to see the planets clearly. With clear skies, you can enjoy this rare celestial spectacle on February 28, 2025.
Note: For January 21, 2025, six of the seven planets will align, with Mercury missing from the lineup.
