On Friday, the planets Mercury, Venus, Mars, Jupiter, and Saturn will be visible in the order of their distance from the sun.
Amateur astronomers are preparing for a heavenly treat from Friday as the five planets visible to the naked eye line up in order of their distance from the sun across the pre-dawn sky.
Mercury, Venus, Mars, Jupiter, and Saturn may be visible before the faintest, Mercury, disappears in the morning glare.
It is not uncommon to see two or three planets close together, but the five that can be spotted with the naked eye have not appeared in order, as viewed from the northern hemisphere.
Edinburgh University's exoplanet characterization chair prof Beth Biller said, "This is cool." "Many stars have worlds. Our solar system's five 'naked eye' planets are all visible.
When viewed from Earth, the planets' short orbital plane makes them appear near to the ecliptic. The five planets will rise Friday morning, but they may not be seen together until later this month.
The public astronomy officer at Royal Museums Greenwich, Dr. Greg Brown, said that Venus and Jupiter would be the easiest to see. Mars and Jupiter would be visible from about 2.45am UK time.
Saturn rises at 1.30am, although like Mars, it's hard to see at dusk. Mercury will be the hardest to notice because it rises at 4.30am and stays near to the horizon.
