Gravitational Influence
(Hill Sphere):
| 0.012 AU / 1830000 km
| Max Stable Prograde Moon Orbit:
| 0.004 AU / 650000 km
| Max Moon Mass:
| < 0.0001 Earths 1,2,3
3.3147 x Miranda
| Tidally locked if older than:
| > 20 Gyr 4
| Estimated Bond Albedo:
| ~ 0.05 5
Notes:
1 assuming age of 5 Gyr
2 inaccurate for planets with mass < 0.3 Jupiters
3 based on periastron due to high eccentricity
4 orbit may be too eccentric for 1:1 tidal lock
5 from Sudarsky et al. 2000
