A Comparison of the Planets in the Sol System
The nutations of the planets Mars and Earth are investigated and compared. A large number of interior structure parameters are involved in the nutation computations. The comparison between the observations and the computations provides several constraints on these parmeters and therefore allows a better...

Transit searches provide a large number of planet candidates. Before attempting follow-up observations, the best effort should be spent in classifying the light-curves, rejecting false alarms and selecting the most likely ones for real planets. A number of analysis tools has been developed with the...

The earth has, then, more than one motion.The apparent retrograde and direct motion of the planets arises not from their motion but from the earth’s. The motion of the earth alone, therefore, suffices to explain so many apparent inequalities in the heavens. ...
