Seven Planets Align in the Night Sky: A Rare Celestial Event
A Rare Celestial Event: Seven Planets in the Night Sky
February concludes with a spectacular treat for sky-gazers: a parade of seven planets across the night sky. Mercury, Uranus, and Neptune will be visible alongside the typically bright planets such as Mars, Venus, Jupiter, and Saturn. However, spotting all seven won’t be easy, according to astronomers.
The planets will all be above the horizon just after sunset, but Mercury and Saturn will be particularly challenging to see due to their proximity to the sun. "Mercury and Saturn are particularly close to the sun and will be lost in the sun’s glare, though Mercury will get higher and higher each day and easier to spot," said Shannon Schmoll, director of the Abrams Planetarium at Michigan State University.
Tips for Viewing the Planets
Venus and Jupiter will be easier to spot thanks to their brightness, while Mars will stand out with its telltale reddish-orange hue. Neptune and Uranus, however, are not typically visible to the naked eye and will likely require a telescope or binoculars to see.
Pro Tips for Spotting the Planets
- Mercury and Saturn: These planets will be low on the western horizon and best viewed about 30 minutes after sunset with the aid of binoculars.
- Venus: Look for Venus first as it will be the brightest and highest in the sky. Once you find Venus, look below it towards the horizon for Mercury and the crescent moon.
- Jupiter and Mars: These planets will be higher in the sky and more visible as darkness falls.
The Science Behind the Alignment
The reason all the planets seem aligned in the night sky is due to their orbits around the sun. "All of our planets go around the sun in a flat disk," explained Schmoll. "From our perspective on Earth, that disk looks like a curved line across the sky stretching from east to the west. As a result, all our planets will always be seen along this line."
Why February is Special
This February is particularly special because the planets are not spaced far apart but are found along a part of the path, causing them to appear together in the night sky. "This February is special because instead of being spaced far apart, they happen to be found along just a part of the path, so they all show up in the sky at the same time," said Seth Jacobson, an assistant professor in the College of Natural Science’s department of Earth and environmental sciences at Michigan State University.
The Role of the Moon
The Cheshire moon, a thin sliver of the waxing crescent moon, will appear just above the western horizon around 6:58 p.m. ET on Friday. This celestial object is named after the grin of the Cheshire Cat from Lewis Carroll’s “Alice’s Adventures in Wonderland.” Mercury will be a few degrees above the moon, and Venus will be above both Mercury and the moon.
How Long Can You See the Planets?
The crescent moon, Venus, and Mercury will continue to appear in a line through Sunday. Jupiter will be high in the southern sky and remain visible for another couple of months, while Mars, high in the eastern sky, will be observable for another three to four months.
Virtual Telescope Project
If clouds or inclement weather obscure your view, the Virtual Telescope Project will share a live stream captured by its robotic telescopes in Manciano, Italy, located in Tuscany under dark skies.

FAQ Section
Q: When is the best time to view Mercury and Saturn?
A: The best time to view Mercury and Saturn is about 30 minutes after sunset, low on the western horizon, with the aid of binoculars.
Q: How long will Venus be visible in the night sky?
A: Venus will be visible in the night sky until mid-March, after which it will reappear in the morning sky in April.
Q: What tools do I need to see Neptune and Uranus?
A: Neptune and Uranus are not typically visible to the naked eye and will likely require a telescope or binoculars to see.
Did You Know?
The alignment of planets in the night sky is a rare event that occurs when the planets are on the same side of the sun from our perspective on Earth. This phenomenon is a result of their orbits around the sun, which all lie in a flat disk known as the ecliptic.
