| 1. | Like HD 47536 b, mass and semimajor axis are not exactly known.
|
| 2. | The two stars are separated by a semimajor axis of 7.61 AUs.
|
| 3. | Then with semimajor axis " a ", the eccentricity is given by
|
| 4. | The boundary for the semimajor axis is surprisingly sharp for the prograde satellites.
|
| 5. | The semimajor axis is 8-9 AU and its orbital period is 17 21 years.
|
| 6. | Geodesists, by convention, use the semimajor axis and flattening.
|
| 7. | They orbit around each other every 11.6 years with a semimajor axis of 0.4 arcseconds.
|
| 8. | However, it does have a semimajor axis near that of Uranus, making it a Uranus co-orbital.
|
| 9. | The secondary star B orbits A at only 9.8 times the semimajor axis of A's planet.
|
| 10. | However, as the semimajor axis of the Moon's orbit continues to increase, this stabilizing effect will diminish.
