In a simplified model of the Solar System, the planets revolve around the Sun in circular orbits, all in the same plane. Each planet has a different period of revolution. Also, each planet is a sphere that rotates about an axis through its center, but with a different period of rotation. In this model the axis of rotation of each planet is perpendicular to the plane of the orbit.

The table below gives additional information about the planets: their periods of revolution about the Sun and rotation about their axes.

A calendar for a Martian year would contain approximately how many Martian days (not Earth days)?
