I hereby suggest that there may have been plants that were moons of other planets. Mercury may have been a moon of Venus; Pluto may have been a second moon to Earth. We also see an explanation as to where the new planetV113 may have come from. Finally, we see the calculation for the inclination of Venus.

This paper deals with the triangular points and their linear stability in the relativistic R3BP when the primaries are triaxial rigid bodies and sources of radiation. It is observed that the locations of the triangular points are affected by the relativistic terms, radiation pressure forces and the triaxiality of the primaries. It is also seen that for these points the range of stability region increases or decreases according as p >0 or p<0 where p depends upon the relativistic terms, the radiation and triaxiality coefficients.

An equation giving the Energy Dissipated by an aster accelerated in a Gravitational Field (EDGF) is presented. EDGF is applied in the present work to express the Schwarzschild radius and to calculate the total evaporation time of the Sun, of the nucleus of our Galaxy and of any star being collapsing gravitationally. Evaporation times of the planets of the Solar system is tabulated in a model where they are swallowed by the Sun collapsing gravitationally from its stage of red giant up to that of white dwarf. In addition, EDGF is used to estimate the scale of the Solar system (limit of the Solar system) which is an important criterion for the identification of a planet or a celestial object as belonging to the Solar system or not. In this work, the limit of the Solar system is estimated at about 160 AU. All our results are compared with available astronomical previsions.
