TNO, SDO, and Centaur Lists

Table 1: Published Observations

This table lists all the published observations that I have found for each object. It includes phometry (by filter: BVRIJHK), spectroscopy, lightcurves, and any other observational measurements. To get a plot of the discovery and recovery statistics of TNOs, SDOs, and Centaurs (and how many are ``endangered'' or lost), click on the image to the right to get a JPEG image, or get the PostScript version here.

Table 2: Positions and Magnitudes

This table provides very approximate positions and magnitudes. Objects are ordered by RA and grouped by month of opposition. Each object is linked to it's entry in Table 1 for cross reference. To get a plot of the positions of TNOs, SDOs, and Centaurs, click on the image to the right to get a JPEG image, or get the PostScript version here.

Table 3: Objects with Satellites

This table lists all the known multiple TNOs and some of the known parameters. A reference list of related papers is also included.

Table 4: Identification Cross-References

This table lists objects that have numbers and names and cross references them with the provisional designations.

Table 5: Images of TNOs, KBOs, EKOs,...

Unusual Kuiper belt related images

For clarity, I give coordinates to only a few arcminutes precision in these tables. If you are looking for more precise positions or ephemerides, I recommend the following:

• Links at the IAU/MPC:
  • Ephemerides and Orbital Elements
  • minor planet ephemeris generator
  • Dates of last observation of distant objects (it also generates ephemerides). This list is also available ordered in RA.
• The JPL Horizons On-Line Solar System Data and Ephemeris Computation Service.
• The Lowell Observatory Asteroid Observing Services

Also, see the Observer Support page for: past observation information of ``lost'' objects, requests for collaboration, and links to personal web pages providing information about observations made/planned by other observers.
