The planet Mars has a diameter of 6772 km, and it orbits the sun at a distance of 227.9 x 10^6 km. If the sun is assumed to radiate like a blackbody at 5760 K, and Mars has an albedo of 0.15 ( reflects 15% of incident radiation back to space), estimate the average temperature of the Martian surface. Ignore the effects of the thin Martian atmosphere.

NASA has sent satellites to the planet Mars. The method is to put the satellite into a Keplerian orbit whose perihelion is at the position of the Earth and whose aphelion is at the position of Mars. The satellite does not travel to Mars under rocket power; it just moves under the influence of the Sun's gravity. Calculate the number of days the trip to Mars will take.
