If you would want to know what all grants does a Object have, we can make use of below procedure. This will mostly help to get grants from PRODUCTION environment, where developers have restricted access,when we do not have direct access to the main schema.
But before that we need to get access to DBMS_METADATA pkg from DBAs.
SELECT DBMS_METADATA.GET_DEPENDENT_DDL('OBJECT_GRANT', 'EMP','SCOTT') from DUAL;
---------
"
GRANT SELECT ON "SCOTT"."EMP" TO "SCOTT"
"
