I think this means that our sun near-collided with another sun a very, very long time ago, and we've got some pieces of that other solar system in ours today... You got me, as physics and math are Chinese to me, but it's my brother's work, so it must be great stuff!

Sorry, Nature is a subscribe-only website. The article is in the issue released today, and it has been featured in many newspapers and TV/Radio broadcasts, among which include:

Sun Might Have Exchanged Hangers-On With Rival Star (NY Times)

Sun may have captured millions of asteroids (Times of India, based on the NY Times article)


Did close encounter shape solar system? (MSNBC, with video link)

Heh you physics types... here's the MSM reaction to my bro's Nature article/press release that I pinged y'all about yesterday.

Hope you enjoy it!

I thought we already knew that.(?)

Congrats to your brother.

There is a much derided theory that the Sun has a distant companion that is responsible for causing these eccentric orbits and for intermittent waves of comets that crash into the inner solar system. If I read this report correctly, that theory is a bit more plausible now since something odd is now recognized to be at work in the distant reaches of the Kuiper belt and OOrt cloud.

Yes, it could have to do with Ox/Ix(Outer x/Inner x), my concept that Brian Marsden thought might be useful. Think of a solar version of galactic globular clusters : spinning, open spheres or lenticular shapes(2 of them)on slightly different solar radii/orbits. Every 26 million years they pass thru each other, throwing out a few comets, thus being partially responsible for the dinosaur-killer asteroid of 65 million years ago. A possible method of detection : a coded lasar pulse sent out into the ecliptic in a precise wavelength so as to excite known surface molecules on sedna/cometary bodies; basically a cosmic flashlight technique. If you get back an echo of a FAST moving body(at the center of the swarm)...

this link is probably long dead:
Rogue Planet Find Makes Astronomers Ponder Theory
by Maggie Fox
October 5, 2000
Eighteen rogue planets that seem to have broken all the rules about being born from a central, controlling sun may force a rethink about how planets form, astronomers said on Thursday... "The formation of young, free-floating, planetary-mass objects like these is difficult to explain by our current models of how planets form," Zapatero-Osorio said... They are not linked to one another in an orbit, but do move together as a cluster, she said... Many stars in our own galaxy, the Milky Way, may have formed in a similar manner to the Orion stars, she said. So there could be similar, hard-to-see planets floating around free near the Solar System.
