Question

Explain how the mass of the Sun can be determined by studying the motion of Earth around it.​

Answer 1

Answer:

here's your answer

Explanation:

A solar mass is the mass of the sun. Or, more precisely, it's 1.989 x 10^30 kilograms — about 333,000 Earths.

Astronomers use a solar mass as a basic unit of mass. Since most things in space are big and heavy — such as stars, galaxies and black holes — it makes more sense to talk about such cosmic objects in terms of solar masses as opposed to a much smaller unit, such as kilograms.

Answer 2

Answer:

the centripetal force is the earth's mass times the squrare of its speed divided by its distanse

Explanation:

by astronomically the distance to the sun,we can calculate the earth's speed around the sun and hence the sun's mass
