| Suggested name | Raqherla |
| Planet type | Large hot gas giant |
| As seen relative to the fixed stars, it rotates on its axis exactly three times for every two revolutions it makes around Qatar-4. As seen from Qatar-4, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
The polar regions are constantly below 162°K (-111°C). |
