OPPOSITIONS OF MARS

Oppositions of Mars occur at an average interval of 780 days; because of the eccentricity of the orbits, opposition's date and least distance don't coincide, but can be as large as 9 days. In the favorable periheliac oppositions, Mars approaches the Earth within 0.4 astronomical unit; these oppositions repeat at intervals of 15 years or 17 years. Each opposition is followed by a very similar one 79 years later. Mars has a risonance with the Earth of 79 years (15+15+15+17+17) or 284 years or 363 years. Due to the secular orbital variations the least distance between the orbits of Earth and Mars is decreasing: around AD 25000 will be only 0.3613 A.U.
