... This means that we can measure the mass of the planet by measuring the speed of the star. The Sun is much heavier than the planets: MJ/MS = 0.001 and ME/MS = 0.000003 (3×10-6) This means that the Sun’s speed is quite small: 12.5 m/s due to Jupiter and 8.4 cm/s due to the Earth. These speeds can be m ...
