Ephemerides for TNOs & KBOs

An excellent online ephemeris for the TNOs and KBOs can be found (as usual) at astro.com.(*see note below) This will be particularly useful for the upcoming three-part post "Lookout America! Eris is Coming!" where the TNOs will be examined in the US Natal Sibley chart and in the transits to the Sibley chart during the upcoming Uranus-Pluto square.

1) Go to http://www.astro.com
2) Click on "Ephemeris" on the blue sidebar on the left side of the page.
3) Click on "Swiss Ephemeris", and select "Special Purpose Lists" all the way at the bottom.
4) Click on the desired KBO listed (e.g., Eris = http://www.astro.com/swisseph/eris.htm)

Charts at astro.com can be run with the TNOs by using their extended chart selection. Some can be selected from a pre-populated list, while Haumea and Makemake at this time must be manually entered using their permament numbers (136108 and 136472 respectively). It's really easy to figure out (Free Horoscopes>Extended Chart Selection>Additional Objects>Select from Box on Left>Add Haumea & Makemake in "additional asteroids" box below Additional Objects>Click Here to Show Chart>Enter Chart Data, etc.)


(*) All KBO's are TNOs, but not all TNOs are KBOs, e.g. Sedna).
