In the coming weeks, planets Mercury, Venus, Mars, Jupiter, and Saturn will appear to line up from the horizon to the Moon.
This is the first time all five planets—the only ones visible to the naked eye—will line up since 2005.
They will be visible from Wednesday, Jan. 20 to Saturday, Feb. 20.
Dr. Tanya Hill, a curator at the Melbourne Planetarium, told Australian Geographic that one will be able to see the alignment again in August of this year and later in October 2018.
Dr. Alan Duffy, a research fellow at Swinburne University in Melbourne, said that the planets sit on a flat plane but have different yearly cycles.
“There are only a few amazing things in the night sky that can be seen without any equipment,” Dr. Duffy told the publication. He added that this is “something well worth seeing.”
Also if you get the startracker app, you can see them following their alignment. Defiantly going to try to see it. https://t.co/VVVj5NO0yn

In terms of actually seeing the planets, he added that “the big challenge will be Mercury,” as it’s so close the horizon.
According to Phys.org, Venus, Mars, Jupiter, and Saturn have been visible in the morning sky since the start of 2016. “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,” according to the website.
