Planets Might Orbit Backward around Odd Star
Space dot com ^ | 13 February 2006 | Robert Roy Britt

Posted on 02/19/2006 10:49:55 PM PST by SunkenCiv

A developing star has been found to have two disks of material rotating in opposite directions. The discovery hints at a future solar system with planets going this way and that. "This is the first time anyone has seen anything like this, and it means that the process of forming planets from such disks is more complex than we previously expected," said Anthony Remijan, of the National Radio Astronomy Observatory... "The solar system that likely will be formed around this star will include planets orbiting in different directions, unlike our own solar system in which all the planets orbit the Sun in the same direction," said study co-leader Jan M. Hollis, of the NASA Goddard Space Flight Center.

Maybe this applies? For every action there is an equal and opposite reaction.

:') If there's a big wad of crud going one way, and another going the other way, things are just not going to work out well. (':

The next post will have a relevant search link -- jumbo extrasolar planets have been spotted (indirectly) in orbit so close to the parent star that they must have been captured, or spiralled slowly inward due to retrograde orbits, or are newly born as chunks of the stars.

Maybe something catastrophic happened early in the formation of the star's solar system to have those disks orbiting in different directions

There's also the matter of transfer of momentum through tidal forces; satellites in prograde gain momentum and climb to higher orbit, while satellites in retrograde do the opposite. The parent body's rotation rate slows with prograde satellites and accelerates with retrograde satellites. There's also a tidal transfer from satellite to the parent body, which is one reason (for example) the Earth's Moon shows the same face toward the Earth.

Maybe a passage of a star changed its orbits. We know when star's get close to objects it changes it orbits. Maybe a local supernova explosion changed the gravitational orbits.

Or maybe it was a young system and as they mature, gravity could right the direction till all planets revolved in the same direction?

At this point, anything a guess. What is needed is more observational time. My favorite pet theory is a galactic super wave.

My theory is that it takes so much time for things like that to happen that we can only hope to both be in heaven as we find out if either of us were right!

From my post to God's ears! LOL ;-)
