Get ready, astronomy enthusiasts! On the evening of February 28, 2025, the night sky will be graced by an extraordinary celestial event: a great planetary alignment featuring all seven planets of our Solar System. Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars will line up in a stunning formation, offering a spectacle that is both rare and awe-inspiring.
But the celestial wonders don't end there. On January 21, 2025, six of these seven planets—Mars, Jupiter, Uranus, Neptune, Venus, and Saturn—will also appear together in the sky, with Mercury being the only exception. This alignment, though not as complete as the one in February, is still a remarkable sight worth witnessing.
Understanding Planetary Alignments

Planetary alignments occur when multiple planets appear on the same side of the Sun, making them visible from Earth simultaneously. While it's not uncommon for a few planets to align, having most or all of them do so is much rarer. Alignments can involve anywhere from three to eight planets, with five or six-planet alignments being more frequent. The seven-planet great alignment, however, is the rarest and most breathtaking of them all.
The Science Behind the Alignment
The planets of our Solar System orbit the Sun on a relatively flat plane known as the ecliptic. Although some planets have slightly tilted orbits, they generally remain on this plane due to the way stars and their planetary systems form. When a star is born, it spins within a cloud of material, which flattens into a disk. Planets form from the remnants of this disk and continue to orbit in this flat position unless disturbed by other gravitational forces.
Occasionally, the planets align on the same side of the Sun, allowing us to see them all at once. This is what will happen on the evenings of January 21 and February 28, 2025.
How to Watch the Alignment
Your ability to see the alignments, as well as the rise and set times of the planets, will depend on your location. Here are some tools to help you plan your viewing:
