Solar system objects are some of the brightest and fastest moving objects in the sky, requiring of sensitive and modern facilities to study their highly dynamic and seasonal changes. Radio/millimeter/submillimeter continuum and spectral line observations provide a unique spectroscopic window to study these bodies. At these wavelengths details of the bulk physical composition of icy surfaces, the size and albedo of small objects, the composition/dynamics/physics of planetary atmospheres can be measured, as well as monitoring of time variable phenomena for extended periods. Long standing questions in solar system science can be addressed by observations in the millimeter/sub-millimeter regime, such as the origin of the solar system (isotope ratios, composition) and the evolution of solar system objects (dynamics, atmospheric constituents, etc). Small bodies are considered to contain the most primitive material remaining from the formation of our solar system, with cometary ices providing an important source of information about the physical and chemical conditions of the early Solar Nebula. Comparing abundances and cosmogonic values (isotope and ortho:para ratios) of cometary parent volatiles to those found in the interstellar medium, in disks around young stars, and in other bodies across the solar system, we can better understand planetary system formation and the processing history experienced by organic matter. Advances in radio/millimeter/submillimeter technologies now allow for broad-band surveys to search for multiple molecules simultaneously during short lived events (e.g. comet outburst, storms on gas giants), while advances in interferometry can now map different species in the outer planets and conduct sensitive searches for new species and follow seasonal effects.
