Thanks for the link.  Somewhere on this forum or perhaps on the BAUT forum I describe a method for using Gravity Simulator to compute how often Earth gets hit from asteroids.  I exaggerate Earth's size to increase the likelyhood of a collision, then adjust my figure accordingly.  The same method might be useful for anyone wanting to simulate the experiments in this paper.

Earth-Sun Distance Measurement Redefined
 
from http://www.space.com/17733-earth-sun-distance-astronomical-unit.html
 
One of the stalwart units of astronomy just got a makeover. The International Astronomical Union, the authority on astronomical constants, has voted unanimously to redefine the astronomical unit, the conventional unit of length based on the distance between the Earth and the sun.
 
"The new definition is much simpler than the old one," says Sergei Klioner of the Technical University of Dresden in Germany, one of a group of scientists who worked decades toward the change, which took effect last month during an IAU meeting
 
Under the new definition, the astronomical unit (or AU) — the measurement used for the Earth-sun distance — is no longer always in flux, depending on the length of a day and other changing factors. It is now a fixed number: 149,597,870,700 meters, which is the equivalent of almost 92.956 million miles.

Gravity Simulator got a mention in one of Brian Koberlein's posts about orbital dynamics and the Kozai mechanism! http://briankoberlein.com/2014/06/09/twist-shout-2/

Surface features and a polar cap.
Strange it would have a polar cap since its pole is pointing in the general direction of the Sun.
