Find SYS default objects

Hello All,

Oracle 19.21 multitenant

rhel 8

Is there a way to find default sys objects?

For example

select owner, object_name, object_id from dba_objects where owner='SYS' order by object_id;

  OWNER    OBJECT_NAME  OBJECT_ID

________ _________________ ____________

SYS   REAL_SYS_OBJECT            2

SYS  YOULL_NEVER_KNOW            10001

Thanks

Dave
