NOTES
[1] The bond albedo is the ratio of total reflected light to total incident light.
[2] V0 is magnitude in visible light at opposition.
[3] AU = astronomical unit. 1 AU = 149,597,870 km, Earth’s mean distance from the Sun.
[4] Relative to Saturn’s equatorial plane.
[5] The inclination of the equator to the orbital plane.
