Your statement:
“The sun is 1,300,000 times as big as the earth”
Please clarify.
By my calculations:
Sun diameter is 108 Earth diameters
Sun volume is 5,280,000 earth volumes
Sun mass is 332,998 Earth masses
What do you mean by “as big as”?
Otherwise, I agree totally with your statements.
(Source: The Cambridge Encyclopaedia of Astronomy)
The sun is estimated at 1.409 x 10 to the eighteenth power cu km.
The earth is estimated at 1.08321 x 10 to the twelfth power cu km.
The ratio of the two volumes comes out to about 1,280,909 cu km. I call that 1,300,000 times a big.
No, the sun is 1/4 the volume you stated.
Using 4/3 pi Rs^3 divided by 4/3 pi Re^3, and cancelling the 4/3 pi, you get Rs^3 / Re^3. That's 54^3 / 0.5^3, which gives about 1.26 million, which is approx. what abclily said.
