Canadians are set to witness a rare and stunning celestial display as six planets line up in the evening sky later this month, a phenomenon astronomers describe as a “planetary parade.” The alignment is expected to shine brightest on February 28, offering skywatchers a memorable view of the solar system.
According to NASA, Mercury, Venus, Jupiter, Saturn, Uranus and Neptune will appear spread out along the same arc of the night sky across much of North America. While the planets are always moving along similar paths, alignments involving so many planets at once are uncommon.
Raymond Carlberg, emeritus professor of astronomy at the University of Toronto, described the event as a striking illustration of the solar system’s structure.
“It’s a beautiful sight,” Carlberg said, adding that the planets will appear in a tilted line near the western horizon shortly after sunset. “It’s almost like you’re on a spaceship cruising through the solar system.”
In Ontario, the best viewing conditions are expected in northern and rural areas, where light pollution is minimal and horizons are clearer. Urban observers may still spot the brighter planets, but darker skies will provide a much better chance of seeing the full lineup.
Meteorologists say timing and moonlight will also play a key role. Anthony Farnell, chief meteorologist at Global News, noted that the best views will come when the moon is only a thin sliver in the sky, reducing glare and improving visibility.
Viewing conditions will vary across the country. Manitoba is expected to have a chance to see all six planets, while Saskatchewan may be able to spot three of them Jupiter, Saturn and Uranus depending on cloud cover. Parts of the Prairies and Atlantic Canada could also catch portions of the alignment if skies remain clear.
NASA advises observers to look about an hour after sunset, focusing on the western sky. The alignment will remain visible for several evenings and continue over the next month, giving skywatchers multiple opportunities to catch the event.
Of the six planets, Venus, Mercury, Jupiter and Saturn are bright enough to be seen with the naked eye. Uranus and Neptune, however, will require binoculars or a small telescope.
Weather may pose a challenge, particularly in regions experiencing heavy snowfall. Snow can reflect artificial light back into the sky, making it harder to see faint objects. Still, meteorologist Ross Hull of Global News pointed out that cold winter air can often bring clearer, sharper skies once clouds move out.
Experts recommend dressing warmly, choosing locations away from city lights, and ensuring an unobstructed view of the horizon. Allowing about 30 minutes for eyes to adjust to the dark can also improve visibility. Smartphone apps and small smart telescopes can help identify planets and guide observers to the right spots in the sky.
While planetary conjunctions occur every year, Carlberg noted that alignments involving this many planets are far less frequent. In fact, astronomers say another alignment of five or more planets will not occur again until 2040.
The planetary parade will also be visible across much of the United States and parts of Mexico, wherever skies are clear making this a shared North American spectacle for anyone willing to brave the cold and look west after sunset.
