get_category() WordPress Function
The get_category() function is used to retrieve the category object by its ID.
get_category( int|object $category, string $output = OBJECT, string $filter = 'raw' ) #
Retrieves category data given a category ID or category object.
Description
If you pass the $category parameter an object, which is assumed to be the category row object retrieved the database. It will cache the category data.
If you pass $category an integer of the category ID, then that category will be retrieved from the database, if it isn’t already cached, and pass it back.
If you look at get_term(), then both types will be passed through several filters and finally sanitized based on the $filter parameter value.

Return
(object|array|WP_Error|null) Category data in type defined by $output parameter. WP_Error if $category is empty, null if it does not exist.
