Hartley: "333,000 times, actually."
According to Wiki...
Sun Mass - 4.38 X 10 (to the 30th) Pounds
Earth Mass - 1.32 X 10 (to the 25th) Pounds
Is the next line below what your calculation looks like...
3.06 X 10 (to the 5th) - ???
I will guess that the precise radius of the sun has been the subject of disagreement for a couple of centuries?
The volume of the sun (as defined by radius?) is 1.3 million times larger than the Earth.
(4.38 X 10^30) / 1.32 X 10^25 = 3.32 X 10^5, or close enough to 333,000.
For the sun to have one billion times the mass of the earth, even though it has 1.3 million times the volume of the earth, the sun would have to have an average density of nearly 770 times that of the earth. The average density of the sun is only 1.4, while the average density of the earth is 5.52.
Sorry, should have typed ‘volume.’ But whether it is mass, volume, temperature, gravity, our orbit, the moon, and so forth we’re gonna die from global warming about when this decade is over. ;-)
