The size of the shift (Redshift or Blue shift) combined with measurement of the period of orbit tells us how massive an object is. How? How can we know the mass of a planet using redshift or blue shift?
Calculating the force is an unnecessary detour if you are interested in the mass, but it is possible.avito009 said:What if we use the formula F=ma or m=F/a to figure out the mass of this planet? If we observe the wobble can we estimate the gravitational force F? Also if me observe the orbit speed we could get to know the acceleration?
Redshift is a phenomenon in which light from an object appears to be shifted towards longer wavelengths due to the object's motion away from the observer. By analyzing the redshift of light from a planet, scientists can determine its velocity and use this information to estimate its mass.
Yes, redshift can be measured with high precision using specialized instruments such as spectrographs. These instruments can detect even the slightest changes in the wavelength of light, allowing for accurate measurements of redshift and subsequently, the mass of a planet.
Yes, there are some limitations to this method. Redshift can only provide an estimate of a planet's mass and is not a direct measurement. Other factors, such as the planet's composition and density, can also affect the accuracy of the mass determination using redshift.
Yes, redshift can be used to determine the mass of any planet, regardless of its size or location. However, it is most commonly used for planets within our own solar system or those that are relatively close to Earth.
The mass of a planet directly affects its gravitational pull, which in turn affects the redshift of light coming from it. A more massive planet will have a stronger gravitational pull, resulting in a larger redshift of light compared to a less massive planet.
