<p>A recently planet astronomy clock, by which the planetary fiducial mark positions, geometric positions between planets near the sun and the corresponding planetary local time can be expediently real time observed, includes: a Mercury hand, a Venus hand, an Earth hand and a Mars hand, which are in turn mounted on the sun axle center in a traveltime caliber linkage chronology mechanism and indicate that corresponding hour hand axles of corresponding planets rotate a cycle during a solar day respectively, rotating around the sun axle according to the view point overlooked from the north celestial pole of the sun; and a Mercury annulus, a Venus annulus, an Earth annulus and a Mars annulus representing the planetary orbits respectively and arranged in turn on the dial surface from the axle center towards outside, in which the sun axle center in the chronology mechanism can be assembled as a coaxial structure or an uncoaxial structure together with the corresponding planetary hour hand axles and month hand axles, and the annuli are arranged around the corresponding hands respectively in the uncoaxial structure.</p> |
