This is Smartlist To Go (formerly ThinkDB) database contain a listing of the satellites of the 9 major planets and those found around asteroids and minor planets. This database is complete free and will remain so for all future updates. To use this database, select a primary (a planet or MP, a category for minor planet satellites) from the views drop down menu (the leftmost drop down menu underneath the "Moons" title). Then select the entry for the satellite you wish to obtain more information for. Each entry has the following information split into three tabs: Orbital data

• Semi-major Axis (distance from center of primary)
• Period (time it takes to complete one orbit)
• E (Eccentricity, represents shape of the orbit)
• I (Inclination, represents tilt of orbit with respect to the equator of the primary)

Physical data:

• Diameter (size of the satellite)
• Type (represents basic composition and size of body)
• Notes (a short description of the satellite as well as other possibly useful data)

Discovery Data

• Discovery Year
• Discoverer

Fields that I would like to add in the next update or two include albedo and density. Update Description:

- Added S/ 2002 N 4 and S/ 2001 U 2
- New satellites announced today.
- Also updated S/ 2002 N 3 based on recovery data from the last two months. v1.11 (September 29, 2003):
