|Orbit Determination Parameters|
The orbit condition code is 6 so there is still a lot of uncertainty.

- 75 out of 100 clones have a cometary like orbit.
- of which: 16 came on a hyperbolic orbit. The one that had the highest speed had a Vinfinity about 15.2 km/s (Vinfinity = 42.1219*sqrt(-0.5/a) --> the semi-major axis being about -3.82 AU
The time (Year) when they entered the solar system was distributed as follows:
Min. 1st Qu. Median Mean 3rd Qu. Max.
-276249 -148774 -75459 -98680 -33904 -709
In a graphical form:
A look at the nominal asteroid
A look at the clones - "footprint" diagrams
This is shown here ( I have used the R function stat_density2d):
In the diagram above, we can also see the current q-Q of the asteroid together with that of Jupiter and Saturn.
In a similar way, these are the footprints for w-om and e-i:
Analysis of close approaches
These plots show the distribution of close appproaches (number and Dmin distance) between the clones and the major planets.
