Add new asteroid to the database from NASA JPL HORIZONS

After generating the ephemeris file for an object at the you will see the following data at the top:

In order to add that object's orbit to the Minor Planets database of DSO Planner on your Android device:

  1. Open the Settings module from the main screen
  2. Select "Objects Databases" item
  3. Tap the "Minor Planets" line in the list to list objects from that database.
  4. Open the main menu of the database screen (Android Menu button, flick up from the bottom of the screen, or floating menu button if you have it enabled in the Night Mode)
  5. Select the "Add Object" command.
  6. On the "Create new object" screen you need to enter following parameters to fully define the new minor planet's orbit:
    • name1 — any
    • name2 — any
    • comment — any
    • month — value of month from the EPOCH= field
    • year — value of year from the EPOCH= field
    • G — value from G= field (Asteroid physical parameters)
    • H — value from H= (Asteroid physical parameters)
    • M — value from MA=
    • axis — value from A=
    • day — value of day from the EPOCH= field
    • e — value from EC=
    • i — value from IN=
    • node — value from OM=
    • w — value from W= field.
