    When mass of the earth is considered, does it mean that it also consider's the mass of the objects present in the atmosphere of the earth example the particles present in the atmosphere of the earth, I know that they are very light in terms of mass but they are present in a huge quantity...

    Example :
    Lets us consider the mass of single particle present in the air as 0.00000001 gms
    As we know that their are huge amount particles present in the atmosphere, Lets us consider that the number of particle present on the earth as 10^30

    Now,
    0.00000001*10^30 gives me some value which is considerable though its not a very big value that can cause any affect. But i want to know is that is this value considered when calculating the mass of the earth ?

    The mass of the Earth is roughly 6 x 1024kg (1) (2), while the mass of the atmosphere is about 5 x 1018kg (3); i.e. about 1 million times less. The mass of the atmosphere is therefore much smaller than any inaccuracy in the measurement of the total mass, so whether or not it is included is pretty much irrelevant.

    (1) Earth’s Mass
    (2) Earth mass - Wikipedia, the free encyclopedia
    (3) Atmosphere of Earth - Wikipedia, the free encyclopedia

    So, you are saying strange, that concern over the mass of the atmosphere is just a lot of hot air.

    As someone who does not calculate any of that, I would consider the atmosphere to be part of earth's mass, I do not discriminate the gaseous state. I assume that a probe/satellites trajectory is affected by the Gas in a gas giant like Jupiter, and assume the Hydrogen and Helium in the sun have an effect on earth's trajectory.
