| Suggested name | Hyobyu |
| Planet type | Large cold gas giant |
| As seen relative to the fixed stars, it rotates on its axis exactly four times for every five revolutions it makes around NGC 6440 X-2.
The neon has probably photodissociated, and the free ammonium hydrosulfide (NH4SH) has been swept into interplanetary space by the solar wind because of the lack of a ethane layer. |
| Atmosphere | Ammonium hydrosulfide (NH4SH) | 50% |

| Ethane | 0.065% |
| Methane | 0.063% |
