Title: The Birth Environment of the Solar System

Abstract: In his comprehensive review on the birth environment of the solar system, Adams (2010) uses four primary dynamical, chemical, and radiation constraints to conclude that the solar system formed in a cluster with between 1000 and 10,000 members. The existence of the planetoid Sedna, on a highly elliptical orbit disconnected from the giant planets, is perhaps the weakest of these primary constraints. We propose a small Gemini imaging program to followup serendipitous discoveries of distant objets in the outer solar system from a 30 night Dark Energy Camera near earth asteroid survey. The Gemini observations will allow us to determine orbits of these distant objects which will allow us to (1) determine if Sedna was indeed emplaced by a birth cluster and (2) use full orbital population statistics to constrain the birth environment of the sun using this unique fossil record of the earliest history of our solar system.
