With nearly 300 planets now known to orbit other stars, we are now able to use the observational data to place constraints on various properties and on the physical processes at work in planet-forming circumstellar disks. The observed distributions of planetary orbital parameters and planetary masses all bear the signature of of circumstellar disks from which the planets formed, as well as the subsequent dynamic evolution of the planetary system which also depends on disk properties. Both the core accretion model and the disk accretion model of planet formation make distinct predictions of the types of planets that they will produce. Newly formed planets that are still embedded in their natal disks will sculpt the distribution of remnant dust, producing potentially observable signatures. We will examine the properties of known planetary systems to attempt to learn more about planet-forming disks.
