There’s a potentially new dwarf planet in town: 2007 OR10. The early data is still coming in and until the body receives a minor planet number we cannot be absolutely certain of the data. Given that Mike Brown was part of the discovery team, I reckon this body is close to receiving a minor planet number. As soon as that happens, I’ll generate an ephemeris and it will be on my Galactic Trilogy CD and those having it will receive an update.
Here’s what we know. It was discovered on July 17, 2007 and presently resides at slightly more than 0 degrees of Pisces (I get 0 Pi 04). According to initial data the body is now direct and remains so until late May where it retrogrades at 1 Pi 23 (approximately). It is strongly inclined at 30.6 degrees to the ecliptic with a reasonably high eccentricity of 0.54. According to today’s data, the body orbits the Sun every 605.41 years and is slightly smaller than Sedna.
NOTE: 1/14/09, Since I posted yesterday, the data on this body has changed such that the orbital period is now estimated to be 552.5 years and the estimated perihelion degree shifted more than four degrees from its originally estimated position. NASA data posits it at 0 Pi 22 and when I force the data into Solar Fire I get 0 Pi 15. Now the orbital period is assumed to be slightly less than that of Eris. Eccentricity is now 0.501 and inclination 30.7, again reminding us until astronomers refine its orbit, too much speculation on position and such should be done with great reserve.
All of the numbers in the above paragraph should be considered preliminary and should not be used for conclusions or firm statements. Usually when these objects are found the position of the north node remains reliable. For 2007 OR10 the ascending node crosses the ecliptic at 6 Pisces 52.
I have found that the degree of ascending node and perihelion of such objects contribute to the body’s astrological significance. As soon as the object receives a minor planet number, I’ll conjure up some speculative keywords. In the past, other astrologers and I have found these keywords remarkably accurate and insightful in delineation.
Bottom line: Get ready. Soon there will be another dwarf planet of the scattered disk variety yearning for inclusion by modern astrologers.
