WOW: High-Desert Telescope Spies Planets Being Born

WOW: High-Desert Telescope Spies Planets Being Born – http://huff.to/1tLL6xk

Capture of some debris is an obvious reason for early formation. 

If something only 500 feet across falls into an orbit it will clean it of dust and keep growing until there is nothing to add.

It just needs to come in at the right speed and angle to make an orbit and with enough speed that after possibly slowing due to dust it will still have the momentum to stay in orbit. 

Look at the cloud of mini planets beyond Pluto, if any of those fell at the right speed and angle into a dust cloud they’d grow rapidly.
