P100Oms Uranus Trojan?   Message List  
Reply Message #25850 of 26727 |
Could we have a uranus trojan on our hands? The first four sets of observations
available on NEOCP currently give the following elements:

P100Oms
Perihelion 2053 May 26.294451 TT = 7:04:00 (JD 2471048.794451)
Epoch 2011 Jul 27.0 TT = JDT 2455769.5 Ur: 0.7678 Find_Orb

n 0.01178013 Peri. 333.53195 -0.73404352 -0.67826697
a 19.1294492 Node 163.61868 0.64231709 -0.70952696
e 0.1244084 Incl. 6.85767 0.22047418 -0.19111616
P 83.67 H 8.5 G 0.15 q 16.7495849 Q 21.5093135
From 12 observations 2011 July 25-27; RMS error 0.391 arcseconds

Which would place the object into a zone of stability as described by Dvorak,
R.; Bazsó, Á.; Zhou, L.-Y. in Where are the Uranus Trojans?

Thoughts: As a rule of thumb, not strict, trojan orbits are more stable with a planet that does not have massive neighbors both inside and outside of it....

A strange coincidence, here http://www.minorplanetcenter.net/mpec/K11/K11O47.html and here http://www.minorplanetcenter.net/iau/lists/NeptuneTrojans.html 2004...

Hi Tomas, My apologies; Find_Orb has misled you here. With this short an arc and this great a distance, the orbit is almost completely indeterminate....
