The Cold Classical Transneptunian objects (TNOs) are one of the least processed solar system subpopulations comma making them a perfect place to test planet formation hypotheses. One of the most favored planetary formation models is the streaming instability comma which predicts that binaries should be extremely common comma especially among the Cold Classical. It also predicts that the spins of individual binary components will be well aligned with the binary orbit. Unfortunately comma to date comma this prediction has been difficult to test comma but with increasingly long observational baselines comma non-Keplerian orbital analysis is able to precisely measure both the shapes and spin poles of individual binary components. With these measurements comma a quantitative test of the streaming instability model of planetesimal formation can be completed. In this program comma we request 8 orbits to precisely measure the spin poles and shapes of Cold Classical TNOs comma which will enable a detailed test of planet formation models.
