| | Polis (Site not responding. Last check: ) |
 | | As are all supergiants, Polis is losing mass via a strong wind, through which it loses about a millionth of a solar mass a year at a wind speed of 600 kilometers per second. |
 | | Far beyond the close double are Polis B (magnitude 8.04 at 17 seconds of arc, at least 29,000 Astronomical Units away), C (10.99, 26 seconds, 44,000 AU), D (9.5?, 47 seconds, 80,000 AU), and E (9.25, 51 seconds, 87,000 AU). |
 | | Polis D is no longer listed with the group, and may just be line of sight. |
