Stargazers will be able to see the phenomenon best on Friday, June 24.
Five planets are in rare alignment and will be visible from Earth next week. For the first time since December 2004, Mercury, Venus Mars, Jupiter, and Saturn line up in this order.
Sky & Telescope says that it's common to see a combination of three or more planets very close together. However, five planets are rare.
According to the American Astronomical Society science magazine, the planets are aligned in their natural order with the Sun. This is quite remarkable.
The five "naked eye" planets could be seen beginning June 3, and 4; the lineup was visible with binoculars, but only for about 30 seconds before Mercury disappeared in the sun's glare.
On June 24, however, a viewing will be at its best. Even though the distance between Saturn and Mercury is increasing, it is becoming easier to spot Mercury. It will also become progressively easier for all five planets to be seen, Diana Hannikainen (observing editor at Sky & Telescope), said.
Michelle Nichols, director for public observation at the Adler Planetarium, stated that you can catch the planet parade by looking toward the east or south.
Prof Green says that this is not always true for planetary consorts due to our view from Earth, which looks into the solar system.
According to Prof Lucie Green, a space scientist and chief stargazer for the Society for Popular Astronomy, the planets look "like a string of pearls that extends from the horizon," he explained.
Although the conjunction was most visible on Friday morning, it will still be visible from most of the world until Monday.
