Since its construction in the late 1970s, the Very Large Array (VLA) has been the worlds premier centimeter-wavelength interferometer. With an upgrade which completed in 2011, it still remains one of the world’s most productive telescopes, at any wavelength. From distant galaxies to bodies in our own solar system, nearly every kind of object has been observed with the VLA, with often surprising results. Here I will concentrate on observations of bodies in our solar system. At centimeter wavelengths, observations with the VLA are able to probe into the deep subsurfaces of solid-body planets, and into the deep atmospheres of those bodies which possess them (giant planets and Venus). I will present results from observations of all of the terrestrial and giant planets, as well as icy bodies (satellites, dwarf planets, and TNOs), and asteroids, and including both passive and active (radar) observations. I will finally briefly cover the future of the VLA – the next generation VLA (ngVLA), a proposed instrument to replace and significantly augment the capabilities of the VLA.
