Problem

Venus is a planet in the Solar System. The following data are given: Orbital period of Venus

=225\,\text{days}

Orbital period of Earth

=365\,\text{days}

(1) Calculate the ratio

\frac{\text{orbital radius of Venus}}{\text{orbital radius of Earth}}

. (2) Explain how observations of the motion of the planets allow scientists to determine the mass of the Sun.
