P4_8 The Solar Escapee

Abstract

The paper investigates the circumstances in which a planet with an orbital radius of 1 AU from the Sun would escape the solar system due to the force supplied by the solar radiation pressure of the Sun. It is found that Earth, while fixing the mass, would require a radius above 3.06×10²⁶ m before it would be ejected from the solar system. Alternatively a planet with the same density and orbit as Earth, but an unfixed mass, would require a radius below 2.76×10^-7 m.
