UML 2.5 standard hierachy of diagrams (see UML 2.5 diagrams overview), shows class diagrams and object diagrams as completely unrelated
Some other authoritative UML sources state that component diagrams are deployment diagrams containing only instance specifications are also special kinds of object diagrams

Notes
Architecture of the system as deployment (distribution) of software artifacts to deployment targets
Components were directly deployed to nodes in UML 1.x deployment diagrams
In UML 2.x artifacts are deployed to nodes, and artifacts could manifest (implement) components. Components are deployed to nodes indirectly through artifacts.

Use to describe
Elements
An interaction by focusing on the sequence of message that are exchanged

destruction occurrence
Use to show
Elements
the interaction between lifelines where the architecture of the internal and how this corresponds with the message passing is central

Use to
Elements
Note
focus on the overview of the flow of control where the nodes are interactions or interaction uses
The Lifelines and the Message do not appear at this overview level
That can only have inline interactions or interaction uses instead of invocation actions
