How much more massive is Jupiter than the Earth? (The mass of Earth is about 5.98 x 1024 kg)
The value we have just calculated is the combined masses of Jupiter and Callisto! Their mass is in units of the Sun's Mass (MS) - we can convert this to
- units which are more familiar to us like kilograms by multiplying this answer by the scale factor (1.99x1030 kg/1 MS):
(MJupiter + MCallisto) = ( MS) (1.99x1030 kg/1 Solar Mass) =
_______x_10___ kg
(I have already written the x 10 so you are reminded to write the exponenet of 10 in the scientific notation expression of your answer). Since you know from looking at pictures of Jupiter with its Galilean Satellites (look in your book at a picture if you have not already), that Callisto is much smaller than Jupiter - in fact it is less than 0.001 of Jupiter's size or mass, so the number we have just calculated for (MJupiter + MCallisto) is almost the same as MJupiter .
