Gravitational Influence (Hill Sphere):
| 0.121 AU / 18140000 km
| Max Stable Prograde Moon Orbit:
| 0.043 AU / 6530000 km
| Max Moon Mass:
| > 10 Earths 3,4
| Tidally locked if older than:
| > 20 Gyr 5
| Estimated Bond Albedo:
| ~ 0.7 6
Notes: 1 from planet formation models of Burrows et al 2 from planet formation models of Burrows et al 3 assuming age of 5 Gyr 4 based on periastron due to high eccentricity 5 orbit may be too eccentric for 1:1 tidal lock 6 from Sudarsky et al. 2000
