Mars will be closest to Earth on January 12. And the moon and Mars will appear super close together on January 13, so close that - for some lucky observers - the moon will pass in front of Mars. Then - on January 15-16 - Earth will sweep between Mars and the sun, bringing Mars to opposition for the first time in 2 years! Full moon and Mars at its best … wow. Join EarthSky's founder Deborah Byrd at 12:15 p.m. CST (18:15 UTC) LIVE Thursday, January 9, for charts and insights.
