... Mars to Appear Normal this August . ... October is the best month to see Mars this year. ... As Earth catches up to Mars in their respective orbits around the Sun, Mars will keep rising earlier in the night. On 2005 October 30, Earth will have caught up to Mars and the planets will be the nearest to each other in their orbits -- this time around. On October 30, Mars will be nearly opposite to the Sun, rise at sunset, set at sunrise, and appear highest and brightest around midnight. ...
