1The five major planets in our solar system have lined up in a rare formation that sky watchers can see with their own eyes.
2Astronomers say the formation is expected to remain in the sky through the rest of June.
3The planets involved are Mercury, Venus, Mars, Jupiter and Saturn.
4They are the brightest planets in the solar system.
5Seeing two or three major planets close to each other can be a common sight.
6But the American Astronomical Society said in a statement that seeing all five together is rare.
7The last time such a planet formation happened was in December 2004.
8The society said the best time to watch the five planets is shortly before the sun rises.
9They will be "stretching across the sky from low in the east to higher in the south," the statement said.
10Some astronomers are calling the event a "planet parade."
11A map published by the Astronomical Society's Sky & Telescope magazine shows the planets appearing from left to right in this order - Mercury, Venus, Mars, Jupiter and Saturn.
12Mercury will appear at the lowest point on the horizon.
13People in the Northern Hemisphere should look toward the east-southeast horizon, while those in the Southern Hemisphere should be looking toward the east-northeastern horizon.
14The planets should be visible without special equipment such as a telescope.
15But binoculars will be helpful.
16Cloudy weather will also affect visibility, so astronomers suggest some planning for the best experience.
17"If it's cloudy on the dates of note, you still have all the mornings in between to take in the view of the five naked-eye planets adorning the southeastern horizon," the society said.
18"Just make sure you set your alarm and wake up on time."
19Mercury is the most difficult to see because it is closer to the glow of the sun.
20But the other planets should be easy to see, even without the use of binoculars, for several more days.
21On June 19th, the American Space Agency NASA tweeted about the beginning of the unusual planet lineup.
22"Look up starting tonight to see Venus, Mars, Jupiter and Saturn spread out and appear to line up in the sky."
23NASA noted that on June 23, sky watchers got a special treat, when the "crescent moon" joined the lineup.
24A "crescent" describes the shape of the moon as it appears early in its first quarter or late in its last quarter.
25During this period, only a small edge of the moon is visible and is lit up by the sun.
26As June ends, the planet parade will come to an end.
27Astronomers predict the next chance to see the five-planet formation will be March 2041.
28NASA says June is also a good time for more serious sky watchers to observe one of the best-known "globular star clusters."
29These "clusters," or groups, are spherical collections of stars gathered closely together at their centers.
30They can include tens of thousands to millions of stars. They orbit the centers of many galaxies.
31The one currently most observable is called M13, also known as the Hercules Cluster.
32But the space agency notes that binoculars or a telescope will be necessary to see it.
33"Find M13 in the constellation Hercules, which is high in the east in the first couple of hours after dark in June," NASA advises.
34A constellation is a group of stars that forms a shape in the sky and has been given a name and has a story behind it.
35The stars in M13 are thought to be around 12 billion years old.
36That is nearly as old as the universe itself, NASA notes.
