This tool provides a list of small-bodies only (asteroids and/or comets) which are likely contained in the specified field on the specified date/time.

Current Settings

Observation Time [change] :  {current time and zone}
Observer Location [change] :  not defined
Search Region [change] :  Corners (R.A./Dec. ) = ( / ), ( / )
Observer Constraints [change] :  Max. Output=20

Specify Observer Location:

Set observer location (the "coordinate origin") using one of the three optional sections below.

Specify a topocentric observer location by choosing from a list of predefined astronomical observatories, major cities on Earth, or by giving the latitude, longitude, and altitude.


Specify Origin: Named Body or Site

   

Use observatory code numbers (if you know them) or names. For example, enter "675" to select the Palomar Mountain main site. Or, enter "palomar" for a list of matching sites.

Specify Origin: Topocentric Coordinates

Longitude and Latitude can be entered as either "degrees minutes seconds" or decimal degrees. In either case, they should always be positive and use the appropriate East/West and North/South selections. If entering "degrees minutes seconds" use spaces or commas between elements. If Altitude is unknown, zero can be used for optical sites without much loss of accuracy.

Longitude: (degrees )
Latitude: (degrees )
( above the reference ellipsoid {WGS-84/GPS})
