Both objects formed among the rocky and icy protoplanets beyond the Solar System's «ice line» now located around 2.7 AUs, but the early development of Jupiter apparently prevented such large protoplanets between the gas giant and planet Mars from agglomerating into even bigger planetary bodies, by sweeping many into pulverizing collisions as well as slinging them into the Sun or Oort Cloud, or even beyond Sol's gravitational reach altogether.
