troubles with Xephem tracing 2011ES4 passage through the solar system


 

Dear fellow Xephemonauts,

I recently tried to visualize the passage of Apollo near-Earth asteroid 2011ES4 through the solar system, but the plot shows it's position somwhere unexpected.
I double checked it on JPL Solar System Dynamics, but get a very different result.

I attached the two image files. The dates for both plots are the same: September 1st 2020, 0:00h UTC
I fetched the latest astorb.dat from the Lowell Minor Planet Services.

Has anybody an idea?
