Specify the Target Body

Choose a method for specifying the target body:

Lookup the Specified Body


[[ search.sstrError ]]
[[ search.error ]]

To restrict your search to only small-bodies or only major-bodies, use the pulldown menu to the right of the Search button above to select the desired filter.

Examples:

  • mars - search for bodies containing “mars” (case-insensitive). If the search filter is set for all available bodies, you would get a list similar to the following:
    • MB: Mars (the planet Mars)
    • MB: Mars Barycenter (the dynamical point corresponing to the Mars-system barycenter)
    • a list of several spacecraft containing the word or substring “mars”
  • eros - search for bodies containing “eros”. This should result in a unique match of the small-body 433 Eros.

  • 10 - search for bodies with either a JPL ID of “10” or a small-body IAU-number of “10”. The resulting list would look similar to the following:
    • MB: Sun [Sol]
    • SB: 10 Hygiea
  • 1998 SF36 or 1998sf36 - search for a small-body with designation “1998 SF36” (case-sensitive). This should result in a unique match of the small-body 25143 Itokawa (1998 SF36).

See the Horizons manual for more information.

Specify Target Body using TLEs

Specify 1-750 sets of SGP4/SDP4 TLEs (Two-Line Elements) in standard format to define an Earth-orbiting spacecraft not already available in Horizons.

Specify Small-Body Heliocentric Ecliptic Osculating Orbital Elements

Data-entry method:
This data-entry method is currently experimental and thus unsuppported. Use at your own risk.

Specify the object on a separate line with Object: object_name_designation_here followed by appropriate osculating orbital elements and optional parameters as field-name=value pairs.

Example:

Object: Asteroid 2000 Herschel
 H= 11.186  G= 0.15
 EPOCH= 2456836.5
  EC= .2972947637124179  QR= 1.67279822872772  TP= 2457504.840305437735
