Blender export stl file is larger than obj file

The total number of facets is more than 9000. The OBJ file exported is less than 1M, and the stl exported is more than 4M. Does anyone know what this is? Thank you for your reply and guidance

stl file size is fundamentally proportional to the number of faces in your model (after implicit triangulation), so having a file that big means that your mesh has a a lot of faces. It's either detailed, or many faces are redundant (unnecessary subdivision).

I would like to know more about the difference between these two types of files,
and why one should use one or the other in specific.
What is the MTL file that is generated next to the OBJ in Everpano?
Can you get the same result, using any of the three files mentioned? OBJ, STL or depth_file-format?
