Title: VENUS AND MARS: THE CLOSEST PLANETARY ANALOGUES TO COMETS
Observer: DENNERL

ABSTRACT
The recent discovery of unexpectedly bright X-ray emission from comets has led to increased interest in X-ray studies of solar system objects. It has demonstrated that even in our immediate astronomical environment surprises may be waiting for being discovered. With their carbon and oxygen rich atmospheres and the absence of strong magnetic fields, Venus and Mars represent the closest planetary analogues to comets. Soft X-ray observations provide a sensitive tool to study such atmospheres, in particular any outgassing effects. AXAF is the first imaging X-ray satellite which is able to observe Venus, and Mars at opposition, when it is closest to Earth.
