Object oriented anything involves working with objects - pieces of code and
state that are normally inextricably tied together.  Access to the state of an
object is done via the code (called methods).

Most OO systems allow you to incrementally develop new object types (called
classes) via a subclassing mechanism.  Subclassing lets you take an object that
allows specific operations and specialize it, benefiting from the code and
state of the existing class.

OO provides a high level of data abstraction and encapsulation. Because of
this, it allows you to view a problem in terms that are closer to your real
world exprience, which IMO is the biggest single benefit of the OO paradigm.
After all, anything I can do with an OO language, I can do with a procedural
language as well.  OO Languages take the OO paradigm and make it easy to
implement your model in code.
