How many times bigger is the earth than a nucleus.

Atom: It is believed for many years that atom is the smallest entity to observe in the universe having the diameter of an ordinary hydrogen atom around 2.50×10⁻¹¹, for which more research was carried out and then we found out that it too has some number of sub-atomic particles called as the electrons and the nucleus(positrons and quartz) in the center of the atomic structure.

Planet Earth:

The celestial body which is possibly the only habitable place to live inside the universe has an enormous body. While, the whole structure of the planet is composed by the small units or building blocks called as atoms. The earth's diameter is around 1.3×10⁷ meters.So, its obviously much larger in size.

Explanation:

How to calculate the difference:

The atom has a smaller size or diameter so, we will suppose a random figure for that, so, we will have the diameter of an atom's nucleus  equals to around 2×10⁻¹⁵m in total and its diameter is about 1×10⁻¹⁰ m.

So, we will now figure out things like dividing the larger value on the smaller, in order to evaluate a model for the atomic size.

the cell theory states that all living things including animals, as well as plants, are made of cells.
