For the first time in more than 10 years, it will be possible to see all five bright planets together in the sky. Around an hour or so before sunrise, Mercury, Venus, Mars, Jupiter and Saturn, the five planets that have been observed since ancient times, will appear in a line that stretches from high in the north to low in the east.

The planets are visible from right across Australia in the dawn sky. You can start to look for the lineup from Wednesday, January 20 and it can be seen right through until the end of February.

Venus, Mars, Jupiter and Saturn have been in the morning sky since the beginning of the year. Jupiter is bright in the north, next comes reddish Mars, followed by pale Saturn and lastly brilliant Venus, which shines above the eastern horizon. It is the appearance of Mercury that makes the family complete.

Mercury has just transitioned from an evening object to a morning object. At first it will appear quite low to the eastern horizon and of all the planets it is also the faintest, so it will be hard to see to begin with. However, Mercury will continue to rise higher each morning and by early February it will sit just below bright Venus.

Dates with the Moon

If you need something a little more to get you leaping out of bed before sunrise, then here are the dates to mark in your calendar. From the end of January, the moon will travel by each planet and can be used as an easy guide for your planet-spotting.

On January 28, the moon will be right next to Jupiter. Come February 1, the moon (in its Last Quarter phase) will be alongside Mars, then on the following morning it'll sit just below the red planet. On the morning of February 4, the crescent moon will be near Saturn. Then on February 6, the moon will be alongside Venus and on February 7, a thin sliver of moon will sit below Mercury.

From January 28 through to February 7, the waning moon will travel through the line up of planets, passing each one in turn. (Museum Victoria/Stellarium)
