After World War I, Charles de Gaulle still served with distinction in Poland. His job was to assist the country during the Poland and Soviet War in 1919 to 1921. To honor him, Poland gave him the Virtuti Militari. It is considered as the highest military award in Poland.
One solar day (the time from noon to noon on the planet's surface) on Mercury lasts the equivalent of 176 Earth days while the sidereal day (the time for 1 rotation in relation to a fixed point) lasts 59 Earth days. Mercury is nearly tidally locked to the Sun and over time this has slowed the rotation of the planet to almost match its orbit around the Sun. Mercury also has the highest orbital eccentricity of all the planets with its distance from the Sun ranging from 46 to 70 million km.
