Re: "about ten times that of Jupiter – or ten times 1.898×10^27kg"
Alain obviously meant 2 significant figures instead of decimal places, and Alain is right, anything much more precise is meaningless. It is like giving the distance from London to New York to the nearest 10 whole miles (3470) which is sensible or to the nearest inch / cm which is so precise it becomes meaningless.
