Tonight, skywatchers across the United States will have the chance to witness a rare astronomical event: seven planets will align in what is called a planetary parade. The planets involved are Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn. This event will only last a short time, but it’s a fantastic opportunity for those interested in astronomy.
What is a Planetary Parade?
A planetary parade occurs when several planets align closely in the sky along a path called the ecliptic plane. This creates the illusion of a lineup in space. While the term “planet parade” isn’t used by scientists, alignments of multiple planets, especially four or more, are a rare and exciting occurrence.
When and Where to Watch the Planetary Parade
The best time to see this alignment is just after sunset on February 28, 2025. The optimal viewing conditions are in a dark location with minimal light pollution and an unobstructed western horizon. For the best chance to view the parade, head to an area with clear skies.
NASA has noted that while all seven planets will align, not all will be visible with the naked eye. Here’s what to expect:
- Venus will be the brightest and near the Pisces constellation.
- Mars will appear reddish and high in the sky near Gemini.
- Mercury and Saturn will be harder to spot, as they will be low on the horizon near the Sun.
- Uranus and Neptune will require a telescope to see. Uranus will be in Aries, and Neptune will be near Pisces.
How Long Will the Planetary Parade Last?
The alignment will only be visible for a few minutes after sunset. Saturn and Mercury will set quickly below the horizon, making them harder to view. However, the other planets will remain visible in the night sky for a longer period.
When Will We See Another Planetary Parade?
Planetary alignments like this one are rare. The next seven-planet alignment won’t happen again until 2040, so don’t miss out on tonight’s event!
For the best viewing experience, head to a location with clear skies and a wide view of the western horizon. This rare celestial event is a great chance to enjoy the wonders of the night sky.
