# Effect on mass of Earth if it stops revolving around Sun

If the object in motion gains mass, will it affect the change in mass of Earth if it stops revolving around Sun, since mass is responsible for gravity how will be the gravitational force change?

That is because the so-called "relativistic mass" is an effect of different frames of reference. (It is also pretty trivial from the POV of someone at rest with respect to the sun, surpressed by factors of order $\frac{30000\text{ m/s}}{300000000\text{ m/s}} = 10^{-4}$.)
