Neat article about the corkscrew asteroid  ;).  All your links are neat, and posting them here is a good way to keep a catalog of interesting links.

As the article says, this asteroid is similar to 2002 AA29.  There is a Gravity Simulator simulation on 2002 AA29.  I forget if its part of the install package, but it is on the website's Simulations page.  I'll make another simulation of the asteroid described in the article and post it here.

From your first article:

Quote:
Other astronomers have noted that it is possible there are three-object systems yet to be found in the outer solar system. If they are all round and have that certain barycenter thing happening, then they'd be called triple planets under the new definition.

I could get a little stranger than that.  You could have a triple system where the smallest planet by itself is not strong enough to pull the barycenter above the surface of the primary.  But the 2nd largest planet in the system is.  So the smallest becomes a planet by default.

This would be the case in the Pluto system if either Hydra or Nix were large enough to collapse into a sphere.

There's a new Plutosystem animation on the Pluto page showing this scenerio:

Although it doesn't mention what direction he will hit the ball, retrograde makes the most sense as its orbit will decay the fastest.

(Taken from a post on Google Group Planetquest)

[glb]Look, up in the sky - it's another solar system![/glb]

PLANETQUEST) -- If you've ever looked up on a clear winter night, you've probably seen it: Pollux, also known as Beta Geminorum, one of the brightest and most familiar stars in the night sky. And now, scientists have discovered that it harbors a secret: a hidden planet, about three times the size of Jupiter.

The discovery of the new planet, dubbed Beta Genorium b, was announced recently by two separate planet-finding teams, one led by Sabine Reffert and the other by Artie Hatzes, both of Germany. Both teams found the planet using the Doppler (or radial velocity) method, which infers the existence of a planetary companion from its gravitational tug on the host star. The new planetary system is located about 34 light-years away in the constellation Gemini.

http://planetquest1.jpl.nasa.gov/atlas/atlas_skymap.cfm?Star=153

In other planet-discovery news, astronomers have announced the discovery of a fourth planet orbiting the star Mu Arae (a.k.a. HD 160691), located in the constellation Ara. The planet is about half the mass of Jupiter and orbits the star at a distance similar to the distance at which the Earth orbits the sun. Mu Arae is the second extrasolar system known to host four planets.

http://planetquest1.jpl.nasa.gov/atlas/atlas_skymap.cfm?Star=128

The recent discoveries bring the total number of known extrasolar planets around normal, sun-like stars to 193.

http://planetquest.jpl.nasa.gov/Planet_Finder/planetfinder.html

*my own info*
Mu Arae is only 41 Lyr away.  With current technology it is potential possible for us to send a probe to this stellar system taking approx. 200 Yrs to reach it.  and another 41 Yrs before recieving data from it.

"New paradigm" for stable circumlunar orbits:

http://science.nasa.gov/headlines/y2006/30nov_highorbit.htm?list14592

I think this has something to do with Kozai, that critical angle of 39.6° that they mention in the appendix looks awfully familiar...

I bet I know what simulation is running on your computer now  ;D

Even in the linked paper, he does not mention the Kozai Mechanism as the cause.  But his description of why these orbits are unstable describes the Kozai Mechanism quite nicely.  I'd be mad if I were Professor Kozai. >:(

Nice evalution ...
Indeed hard to simulate..must be a mix between fluid mechanics and gravitation .
A couple of days ago I wondered how it is possible to simulate dark matter and the motion of planets in such a field . Suppose the solar system is filled with dark matter fi. the mass of 10 jupiters , but homogeneous . How would the planets behave , or do they already behave in such a way ?

Asteroids missing us  or hitting us ...., when ...?  

There are some beautiful sites on the net like the NEAR site of Nasa/JPL showing the orbits of the known asteroids .  
Some of them allow the generate the ephemerides , which can be used in GravSim .  
In search of a table of forecasted "close approaches" i found among others this site...

http://cfa-www.harvard.edu/iau/lists/CloseApp.html

This site seems to be updated daily ...
In the next 2 years it is known that +/- 314 of them will come close within 0.2 AU ( ca. 8 times Lunar Distance ) to the earth.  The figures of this site can be exported ...
Looking at the distribution of distances ( "miss" distance) the cumulative distribution looks linear ... No  known asteroid of this 314 will hit the earth  , however the line can be extrapolated to the  radius of the earth , showing that one of these ( yet to be discovered ) can hit the earth in a time span of 2 years .  I created an excel file for these ....

Remarkable is the fact that often new asteroids are discovered  on their way to earth , getting pretty close...

Not really news but some info for people outside the UK, which I gather covers the majority of members.
We have a monthly TV programme called the sky at night which covers all things astronomical. Its been running for 50 years with the same (somewhat eccentric) presenter, Sir Patrick Moore. Anyway getting back to the point, you can watch all the episodes from December 2001 online courtesy of the BBC website. Some of the older ones are low quality but quite watchable. So for anyone who is interested here is the link.

Note:

The model of planets forming in vortex in planetary disc was already proposed in a research of 2005:

- http://www.journals.uchicago.edu/doi/pdf/10.1086/498928

This paper, among other things, demonstrates that this model allows the formation of planets more quickly, and in less massive planetary disc, than the old models ( gravitational instability only ).

Stability of the Distant Satellites of the Giant Planets in the Solar System, by Shen and Tremaine (2008),
http://iopscience.iop.org/1538-3881/136/6/2453

Fortunately it's in a free issue of the Astronomical Journal, so you can grab the PDF for free! I've only skimmed it so far, but the very interesting thing is that it says that there can be stable satellite orbits outside the planet's Hill Sphere, which I at least wasn't previously aware of. So check it out if you're interested!

Nice! Seriously, I wonder why scientists don't seem to know about Gravity Simulator.
I was reading an article yesterday about "curiosity-driven science" and how essential it is ( http://www.nature.com/news/2010/101117/full/468347a.html ), and it seems that everything we do on gravsim forums is definitely curiosity-driven - and look at the stuff we find!

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.

yes , that's true Tony , Pluto's pole is more or less pointing to the sun . Strange Nasa believes to see a polar cap . If there's some sort of cap it should be to more to the eqautor . Perhaps that's just what we see in the pictures .
Exiting weeks to come ....
