Geotimes March 2006 Kathryn Hansen	Young Planets Collide Size mattered, astronomers say, when it came to whether or not material in our early solar system stuck together to become today's terrestrial planets. New models suggest that collisions between large objects did not always result in those objects combining, as previously thought.
