All five visible planets will appear together in the morning sky early next year – from about January 20 to February 20, 2016. That hasn’t happened since 2005.
Relative sizes of the four inner planets: Earth, Venus (back row); Mars and Mercury (front row).
The last time that all five visible planets (Mercury, Venus, Mars, Jupiter and Saturn) appeared in the same sky together was over 10 years ago, from December 15, 2004, to January 15, 2005. The next presentation will again happen for a period of about one month, starting on or near January 20, 2016.
All five visible planets will appear above the horizon simultaneously in the predawn/dawn sky from about January 20 to February 20, 2016. Moreover, people around the globe can use the moon to help guide them to this showcase of planets from January 27 to February 6.
By visible planet, we are referring to any solar system planet that is easily viewed without an optical aid and that has been watched by our ancestors since time immemorial. In their outward order from the sun, the five visible planets are Mercury, Venus, Mars, Jupiter and Saturn. These planets are visible in our sky because their disks reflect sunlight, and these relatively nearby worlds tend to shine with a steadier light than the distant, twinkling stars.
Of course, you can catch most of these planets before dawn. Jupiter rises first, in the evening hours, followed by Mars after midnight and then Saturn, Venus and Mercury.
May you be blessed with clear skies for the upcoming planetary spectacle, with all five visible planets taking stage in the same sky from January 20 to February 20, 2016!
Thank you, Skeen! 😀
