By matching the Measured Density to the Calculated Density, you are likely to find values similar to the following: Earth has a core filling about 65% of its interior. Venus: 65%, Mars: 40%, Mercury: 80%, The Moon: 40%.
of the terrestrial planets mercury is next to the least massive after the moon being about 6 percent of earth s mass and next to the smallest in size being less than twice the size of the moon next to the earth however it has the highest mean density about 5 4 g cm3 a point we shall come back to later the general physical characteristics of the terrestrial planets excluding the moon are given in table 1
