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. |

That's one scenario suggested by a recent investigation of a venerable equation that serves as a model for planetary tidal effects. |
