gridloreAstronomers discover possible miniature solar system
Very cool news. And it has an accretion disk! Pity it's so far out, would have made a neat location for the Concordat.
Astronomers peering through ground- and space-based telescopes have discovered what they believe is the birth of the smallest known solar system.
Scientists found a tiny brown dwarf - or failed star - less than one hundredth the mass of the sun surrounded by what appears to be a disk of dust and gas.
The brown dwarf -located 500 light years away in the constellation Chamaeleon - appears to be undergoing a planet-forming process that could one day yield a miniature solar system, said Kevin Luhman of Penn State University, who led the discovery.
It's long believed that our solar system came into existence when a huge cloud of gas and dust collapsed to form the sun and planets about 4.5 billion years ago.
The latest finding is intriguing because it's the smallest known brown dwarf to be discovered with planet-forming properties. If the disk forms planets, the resulting solar system will be about 100 times smaller than our system, scientists say.

I wonder...

Date: 1 Dec 2005 00:19 (UTC)I would tend to think that you could get an orbit that would allow liquid water, that that zone would be very narrow and perilously close to the Roche limit.
A concept I just had come to me is a Europa-like world in a highly eccentric, short orbit. The covering ice melts (at least on one side) on a regular basis.
Imagine the religion that would grow up around that...
