No, because the biomass - the total mass of all people, other animals and plants - of the Earth remains essentially constant. (And the amount of biological mass on Earth is essentially minuscule as well.)
It increases.
earth's elliptical orbit around the sun causes the changes. (science fact: as earth gets closer to the sun, it goes faster.) look up on Google images of "earth's orbit and seasons"
A space vehicle designed to orbit the Earth slowly should be put into a low orbit. Low Earth orbit allows for slower orbital speeds compared to higher orbits, making it more suitable for vehicles designed to move slowly. Additionally, low orbit provides easier access for communication, resupply, and potential crew rescue missions.

The Earth's aphelion - the farthest its present orbit takes it from the Sun - is 152,097,701 kilometres. The other point, the perihelion - the nearest it gets to the Sun on its present orbit - is 147,098,074 kilometres
If the satellite is anywhere near Earth's surface, it will take about one and a half hours to orbit Earth once. As the orbit gets higher, it will take longer - both because it must travel a longer distance, and because it will be slower.
The earth moves around the sun and at certain points the sun is further away from the earth that produces winter but as the earth gets nearer to the sun in its orbit it gets hotter therefore we get summer and autumn and spring in between.
The earth needs to be at a point in its orbit from which the Hohmann transfer orbit between earth and the orbit of Saturnrequiring the least launch energy terminates at the point where Saturn will be when the vehicle gets there.You might want to read that again, slowly. That's as plain as I know how to say it.
because the earth's gravity is pulling the moon towards itself just like earth gets pulled by the sun with the help of its gravity
It changes all the time, as Earth gets closer to, and farther from, the Sun, in its yearly orbit.
The moon is not getting closer but further
Moon gets attracted to the earth's gravity. But this is neutralized by the centrifugal force which pushes it outwards. This is how moon orbits around the earth without colliding into it.
