I assume you mean, scientifically, what are some of the smaller objects. Well, electrons of the atom are very minute objects, but if you want to go beyond that, you can look into neutrinos. They are literally "stardust", and billions of them collide with the earth each second, but because they are so small, they pass through earth's particles, making it hard to detect and examine.
The science concerned with objects of the smallest dimensions is called nanotechnology. Nanotechnology involves manipulating materials on an atomic or molecular scale to create new functionalities and properties. It has application in various fields like electronics, medicine, and materials science.

The Moon is the smallest of the three objects listed
No. At the very least, all objects are composed of matter.
The smallest objects - are meteors. Most of them are smaller than a Basketball.
Bacteria is the smallest cell*it was in my science book*
Resolution in science refers to the ability to distinguish between two separate points or objects. In microscopy, resolution is the clarity or level of detail in an image. In other scientific contexts, resolution can refer to the smallest discernible change in a measurement.
The smallest measurement of time known to science is called a Planck time, which is approximately 5.39 x 10-44 seconds.
Astronomy is the study of celestial objects (Space objects).
That depends what you include under the term "objects". In general, those would be subatomic particles. Many of them are (in a sense) considered to have no volume. Some of them, such as photons and gravitons, have zero mass (rest mass; they will have some mass due to their energy).
