here is no such relationship. The more the mass of the body, the greater is its gravitational force but other factors even determine the number of moons in orbit to that planet. For example, Mars has a lower mass than Earth but still has 2 moons - Phobos and Deimos while Earth has only one moon!

This statement is true. Robert Campin, who is also identified as "Master of Flemalle," was the first great painter of early Flemish and Early Netherlandish paintings. He was a painter of late 14th century. He was the first painter who showed more realistic observation powers. Campin used to paint more rounded characters by modeling light and shades, which gave his painting more sense of perspective and space.
