The period of revolution of earth about the sun is 365.256 days, approximately. The semi-major axis of the earth's orbit is close to $1.4953 \times 10^{11} \mathrm{~m}$. The semi-major axis of the orbit of Mars is $2.2783 \times 10^{11} \mathrm{~m} .$ The period of revolution of Mars, about the sun, is___________Earth days(in three decimal place)
