Mars set for prime time
December 2009: Jupiter and Mars draw the top headlines in December's evening sky.
October 26, 2009
Jupiter and Mars draw the top headlines in December's evening sky. But while Jupiter is nearing the end of its current evening visibility, Mars is just beginning. Mercury joins the action right after sunset starting the second week of the month.
Mars shifts direction against the background stars of Leo the Lion around mid-December. The start of this “retrograde loop” heralds the planet’s opposition in late January.
