- Palapa satellites orbit the earth 24-hour period. If the palapa satellite orbits planet x which has the same mass as the mass of the earth. And the radius is 4 times the radius when it orbits the earth. Then the satellite orbits planet x by?The planet Mars has a satellite, Phobos, which travels in an orbit of radius 9.4 xm with a period of 7 hr 39 min. Calculate the mass of Mars from this information.An object weighs 90 N on Earth’s surface. Determine its weight when it is two Earth radii from the planet’s surface.
