Query form

This Web form is a user interface to the VO-compliant Web service SkyBoT. Fill in the form of your choice and submit the query. Read the documentation if you mind how to do, or just fly over the labels of the input fields to get a quick help.

Cone Search Query Form
Use this form if you want to know which solar system objects are located in a field of view (FOV) of given coordinates and radius at a given epoch. After filling the form, submit the query by clicking on the 'Search Objects' button. If you enter the name of a target in the 'Target' field and press the 'Resolve target' button then it will just resolve its name into its coordinates. Press the 'Search Objects' button to directly post the query. You might have to wait a while before you get a response if your radius is rather large (greater than few degrees).
Resolver Query Form
Use this form if you want to resolve the name of a solar system object into its J2000 astrometric geocentric or topocentric coordinates on the equatorial celestial sphere at a given epoch. After filling the form, submit the query by clicking on the 'Resolve Target' button.
Get asteroid class
Use this form if you want to know the (dynamical) class of one or more asteroids.
Status
Use this form if you want to know the actual status of the database, or if you want to know if a given epoch is covered by a period of time in SkyBoT.

.: Cone Search Query Form :. 
Epoch (UTC):Enter the date or the julian day of the requested epoch (UTC). The date must be formatted as any English textual datetime.
 
Examples: now, 2005-4-16 1:53:34, 10 September 2000, +1 day, +1 week, +1 week 2 days 4 hours 2 seconds, next Thursday, last Monday, etc.
 
Note: the second of time must be an integer value when using ISO format.
 
Limits:
1889-11-13 12h .. 2060-03-21 12h

Target:Target: Enter the J2000 astrometric geocentric right ascension and declination of the FOV center, in hours and degrees
OR
Enter the name of the designation of a solar system object. Refer to the documentation for the syntax.
 
Format of the coordinates: decimal or sexagesimal value
Examples:
9.911337 +16.38380556
9:54:40.81 +16:23:1.7
9 54 40.81 +16 23 1.7
 
Format of the names: enter the official name or number or provisional designation of the target.
 
Limits of coordinates: 0h..24h ; 0°..360°
Objects:Enter a value to retrieve only objects of which position error is lesser than the given value.
 
Format: decimal value in arcsec; 0 implies no filter; default value = 120 arcsec
 Asteroids    Planets    Comets
Radius (arcsec):Enter the box size (XxY) of the FOV, in arcsec. If Y is omitted then the FOV is taken as a square box of XxX arcsec.
 
Format: [XxY] (e.g 1200x900 or 600).
 
Limits: X,Y ≤ 108000 arcsec
 
Note: if you submit a request with a large FOV radius, please be patient, your browser may need some time to process and display the response (from xml to html) which can contain (tens of) thousands of bodies.
Observer:Enter the IAU code of the observatory or 500 for the geocenter, kepler for NASA Kepler/K2 spacecraft, or rosetta for ESA Rosetta spacecraft.   (IAU code list)
Filter:Enter a value to retrieve only objects of which position error is lesser than the given value.
 
Format: decimal value in arcsec; 0 implies no filter; default value = 120 arcsec
Output:Choose the parameters to display. See the SkyBoT documentation for details.  Object    Basic    Obs    All
