The five major planets in our solar system have lined up in a rare formation that sky watchers can see with their own eyes. Astronomers say the formation is expected to remain in the sky through the rest of June. The planets involved are Mercury, Venus, Mars, Jupiter and Saturn. They are the brightest planets in the solar system. Seeing two or three major planets close to each other can be a common sight. But the American Astronomical Society said in a statement that seeing all five together is rare. The last time such a planet formation happened was in December 2004. The society said the best time to watch the five planets is shortly before the sun rises. They will be “stretching across the sky from low in the east to higher in the south,” the statement said. Some astronomers are calling the event a “planet parade.” A 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. Mercury will appear at the lowest point on the horizon.
