In the Primordial Soup
-

Climate Change Biographies
-
Models of planetesimal disks suggest that low relative velocities between the bodies produce accretion (objects hit and stay together) rather than fragmentation (objects break up and disperse).
-
Although planets, moons and planetesimals may seem to be very different astronomically, their common origin shows that this is not so.
