How many times the mass of the sun is that of the earth? this is it!

330000 times
The mass of the sun is nearly 200 billion tons, 330000 times that of the earth
It's about 1.3 million times the size of the earth,
The radius is about 700000 kilometers, more than 109 times the radius of the earth

How many times the mass of the sun is that of the earth? How many times the mass of the earth is that of the moon?

The mass of the sun is 2.0 * 10 to the 30th power, the mass of the earth is 6.0 * 10 to the 24th power, and the mass of the moon is 7.4 * 10 to the 22nd power
310000 and 81x

The mass of the earth and the distance from the sun are known. The motion of the earth around the sun can be regarded as uniform circular motion. What is the gravity of the sun on the earth?
The mass of the earth is 6.0 × 10 ∧ 24kg (6.0 × 10 ∧ 24kg), and the distance from the sun is 1.5 × 10 ∧ 11m (1.5 × 10 ∧ 11m)
There are a lot of answers on the Internet, but I don't know which one is right. I hope my classmates can give me the right answer
Attachment: if you can, please write down the idea of each step~

Add a condition (common sense): the earth's cycle T around the sun is 365 days, that is 3153600 s
Gravity provides centripetal force: F = GMM / R ^ 2 = 4 π ^ 2 / T ^ 2 * r * m = 4 π ^ 2 / 3153600 ^ 2 * 6 * 10 ^ 24 * 1.5 * 10 ^ 11 = 5.6 * 10 ^ 30n
