object name user_objects with object_type = 'TABLE' but in user_tables the table does not exists.

I am not sure how this has happened but below shows the object I have in user_objects of object_type = 'TABLE';

"OBJECT_NAME"  = BIN$BCt8yl57S5G0tJ754zF9NQ==$0

"OBJECT_ID"  =  73472 

 

SELECT * FROM user_tables * FROM user_tables where table_name = 'BIN$BCt8yl57S5G0tJ754zF9NQ==$0';  0 rows returned. 

table_name = 'BIN$BCt8yl57S5G0tJ754zF9NQ==$0';  0 rows returned.   0 rows returned. 

1.  How can I drop this object of object_type table when its not really a table?

2.  Any idea how this type of bad data could have happened?

thanks
