Mars Observation: Great perihelic opposition 2018
On Mars, the northern autumn and southern spring continue, and the southern hemisphere is strongly tilted towards the Sun (and, of course, also towards the Earth). Its angular diameter increases steadily and reaches 20 arc-seconds on June 25. On June 26, Mars begins the so-called retrograde motion, i.e., for some months before, during and after its opposition it moves toward the west as seen from the Earth. This movement is caused by the fact that the Earth moves faster than the Mars around the Sun and our planet just begins to overtake Mars. On the surface of Mars, the South Polar Cap is now very small and shrinks even more. The new North Polar Cap is not visible, it remains hidden under clouds and mist.
