UK NIGHT SKY March 2011
Early March the evening sky is dominated by the planet Mars shining brightly in the constellation of Cancer. Mars is named after the god of war because of it’s reddish colour, which can be clearly seen this month.
Mars is one of the ‘wandering stars’; i.e a planet which moves in the night sky and sometimes appears to reverse direction and go backwards. This is an optical illusion caused by Mars having a much slower orbit of the sun.
A year on Mars takes 687 days, so when Earth ‘overtakes’ this planet, Mars seems to go backwards in the sky.
