Image NASA. Mars, lying above Spica in Virgo, reaches opposition on April 8th when its magnitude will be -1.5 and its angular diameter 15.1 arc seconds. Due to the fact that Mars, and to a lesser extend, the Earth have elliptical orbits, its distance from us at opposition can vary from ~54 to 102 million km. As a result the angular size will vary from ~13 to 25 arc seconds - a major difference.
