Anagami

Anāgāmī: The Non-Returner is a Noble Disciple Ariya-puggala on the 3rd stage of Nobility. 
An anagami (non-returner) has completely eradicated the first five hindrances of the 10 hindrances to enlightenment and never returns to earth or any other world system (planet, solar system). Such a person is reborn to a heavenly realm and attains enlightenment from there.
There are 5 classes of Non-Returners, as it is said e.g. Pug. 42-46:
A being, through the disappearing of the 5 lower mental chains samyojana, reappears in a higher world amongst the devas of the Pure Abodes, suddhāvāsa, and without returning from that world into the sense-sphere, he there reaches Nibbāna.
1. He may, immediately after appearing there in the Pure Abodes or before half of the life-time, attain the Noble path for the overcoming of the higher mental chains. Such a being is called one who reaches Nibbāna within the first half of the life antarā-parinibbāyī.
2. Or, while living more than half of the lifetime there, or at the moment of death, he attains the Noble path for the overcoming of the higher mental chains. Such a being is called one who reaches Nibbāna after crossing half the life-time upahacca-parinibbāyī.
3. Or, with effort he attains the Noble path for the overcoming of the higher mental chains. Such a being is called one who reaches Nibbāna with exertion sasankhāra-parinibbāyī.
4. Or, without effort he attains the Noble path for the overcoming of the higher mental chains. Such a being is called one who reaches Nibbāna without exertion asankhāra-parinibbāyī.
5. Or, after vanishing from the heaven of the Aviha-gods see: suddhāvāsa, he appears in the heaven of the unworried atappa gods. After vanishing from there he appears in the heaven of the clearly-visible sudassa gods, from there in the heaven of the clear-visioned sudassī gods, from there in the heaven of the highest akanittha gods. There he attains the Noble path for the overcoming of the higher mental chains. Such a being is called one who passes up-stream to the highest gods uddhamsota-akanittha-gāmī.
