The mass of the Moon can be found from a modified form of Kepler's third law of Planetary Motion. You need to know the time taken for the Moon to orbit the Earth and the mass of the Earth. Also you need the distance between the Moon and Earth. Let the orbital period be P Moon's mass = Mm Earth's mass = ME Distance apart = D Gravitational Constant = G Then: Mm + ME = (4pi2/G) x (D3/P2) Note: That equation doesn't show up properly on some pages. To clarify, it involves: pi squared, D cubed and P squared. Also, an artificial satellite orbiting the Moon can be used to find the Moon's mass by the same method: mass of satellite (negligible) + mass of Moon = (4pi2/G) x (D3/P2) D is now the distance of the satellite from the center of mass of the Moon and P is the orbital period of the satellite.
It is a method of reading, which helps improve your reading speed.
They use the banana method
A method of recording the location of stars is by taking pictures of them/photography.
Astonomers, like all scientists, dont have one single method ,or "The Scientific Method". They have a wide variey of ways to solve problems.
The post method. ( As opposed to the get method ).
something that is observed and can generally not be measured.
You're probably angling for the answer "Radar" or you could be fishing for the answer "Sonar" instead. To be a little more accurate, the object is not located by "sending out a pulse" of radio energy, but rather by analyzing the energy the object returns after the pusle is reflected off it. We can do the same thing with sound, and we locate things under water by this method. Bats locate insects in the air via sonar.
