The sizes of solar systems

As of last month, 685 multi-planet solar systems (with 1705 planets) have been discovered outside our own. This video shows the relative sizes of those systems compared to ours. Please note:

The size of the orbits are all to scale, but the size of the planets are not. For example, Jupiter is actually 11x larger than Earth, but that scale makes Earth-size planets almost invisible (or Jupiters annoyingly large).
