Answer #1

Mercury Statistics

Planetary Symbol: Name in Roman/Greek Mythology:
Diameter: 4,878 km Rotation Period about Axis:
Mass: 0.33x10^24 kilograms (0.06 x Earth's) Revolution Period about the Sun:
Density: 5,427 kg/m^3 Tilt of Axis:

m + M = 4 2 / G * (D3 / P2 )

0.33 x 10^24 + M = (4 x 3.14^2 / 6.62 x 10^27 ) * (( 5.791x10^7)^3 / 4878^2)

                           = 485.97 x 10^24

Mass of the Sun = ( 485.97 - 0.33 ) x10^24

                        = 485.64 x 10^24 Kgs
