We start by determining the mass of the Earth. Issac Newton's Law of Universal Gravitation tells us that the force of attraction between two objects is proportional the product of their masses divided by the square of the distance between their centers of mass. To obtain a reasonable approximation, we assume their geographical centers are their centers of mass.
Because we know the radius of the Earth, we can use the Law of Universal Gravitation to calculate the mass of the Earth in terms of the gravitational force on an object (its weight) at the Earth's surface, using the radius of the Earth as the distance. We also need the Constant of Proportionality in the Law of Universal Gravitation, G. This value was experimentally determined by Henry Cavendish in the 18th century to be the extemely small force of 6.67 x 10-11 Newtons between two objects weighing one kilogram each and separated by one meter. Cavendish determined this constant by accurately measuring the horizontal force between metal spheres in an experiment sometimes referred to as "weighing the earth."

What scientist studies the function of the sun?
Astronomers study celestial bodies, helio astronomers specifically study suns.
What is the suns mass?
The Suns mass is 1.9891 × 1030 kg or about 333,000 times that of Earth. The Sun contains about 99% of the total mass of the Solar System.
How much does the suns mass decrease every second in tons?
About 4 million tonnes.
What do Doppler shift observations of a spectroscopic binary star enable astronomers to calculate?
They let us see the speed of the stars around the common center of mass. More precisely, the Doppler shift will only detect the component of this speed in our direction - that is, towards us, or away from us.
What do you call people that study outer space and the solar system?
Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.

What is the mass of the earths mass compared to the suns Mass?
ur mother
How much does the sun have mass?
The suns mass is 332,950 earths.
Binary stars can be used to calculate the of stars?
Double stars, also called binary stars, are valuable to astronomers because they are the only stars of which astronomers can easily calculate their mass. They are bound to each other by gravity and orbit about a common center. The time it takes for one star to orbit the other depends on the distance between the two stars and their masses.

How do you calculate a mass of am atom?
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
How do astronomers find the mass of a black hole?
By observing the movement of nearby objects.
How many times as great as the mass of Saturn is the mass of the sun?
The mass of the sun is around 3500 times that of Saturn. 3500 Saturn masses = the suns mass.
What is located in the middle of our galaxy?
A supermassive black hole - with the mass of about 4,000,000 Suns.
What element makes up seventy five percent of the suns mass?
Hydrogen.
