Tonight's the night for the parade of all seven planets - BBC Africa

January and February have been fantastic for amateur astronomers, with six planets visible in the night sky. Now as an extra treat, and for one night only, on 28 February Mercury can be seen with the naked eye joining this planetary alignment.  It’s the last of 5 days it will be visible from Earth in an arc of planets. Scientists say it’s the closest we will come to a full planetary alignment in a lifetime. #planetaryscience #planetaryallignment Subscribe: http://bit.ly/subscribetoafrica Website: https://www.bbc.com/africa Facebook: https://www.facebook.com/bbcnewsafrica/ Twitter: https://www.twitter.com/bbcafrica/ Instagram: https://www.instagram.com/bbcafrica/
