Up to 150 tons of meteorite fragments slam into Earth every year.
So I think the planet is getting heavier.

Weight is the product of mass and the gravitational constant of the mass (w=mg). However, the earth's gravitational constant is dependent on the amount of mass (g=GM/r^2). So the equation for weight can be rewritten as w(m,r)=m*f(m,r). If the mass or mean radius changes, even negligibly, the weight is not constant. For most calculations with changing mass/radius, the difference is usually less than the error tolerance of the problem and can be disregarded.

The weight of the Earth changes depending on the local gravitational field that you weigh it in.
The mass however, which is probably what you mean, increases by the collection of small amounts of space debris, although the gain is insignificant compared to the total mass.

The Earth gains mass, not weight, continuously...about 10^6 to 10^8 kg per year.
This far exceeds the piddling amount of mass lost due to spacecraft launches, etc.

Though it's not a question anyone can accurately answer, we can only theories it. But I would speculate that yes, simply because the birth rate far exceeds the death rate, and people are living longer. more people = more mass.....but wait, we harvest mass (food) in order to feed those people so one would think that we would displace that mass proportionally.....but there are alot more of us now then there were 500 years ago.
As we burn fule, and it changes states, so dose it's mass and weight.

yes and no.
why?
when objects like space craft flies out to the space, there are materials made up of earth materials which is integrated to the earth. it reduces the actual weight. so it is not constant.
yes, because the actual weight that is reduced when these objects goes out from the earth, it will not affect or it is negligible when it comes to the proportionate weight.

The mass of the earth varies as we lose parts of the atmosphere into space and gain bits of asteroids and other debris. Also we jettison metal ourselves.

the earth has no weight,only mass.

I wouldn't think so due to water evaporation, rainfall, plant and animal growth and decomposition, stuff like that.

no i don't think it is cause we get stuff from space. besides rosie keeps gaining weight.
