The proceedings include papers written by American and Soviet scientists who examine the current theoretical understanding of how the planets were formed and how they evolved to their present state. They assess the type of observations and experiments that are needed to advance understanding of the formation and evolution of the solar system based on the current theoretical framework. 606 $aPlanets$vCongresses 606 $aPlanetary science$vCongresses 606 $aPlanets$xResearch$zUnited States$xInternational cooperation$vCongresses 606 $aPlanets$xResearch$zSoviet Union$xInternational cooperation$vCongresses 615 0$aPlanets 615 0$aPlanetary science 615 0$aPlanets$xResearch$xInternational cooperation 615 0$aPlanets$xResearch$xInternational cooperation 676 $a523.4 701 $aDonahue$b Thomas M$01806706 701 $aTrivers$b Kathleen Kearney$01805666 701 $aAbramson$b David M$01805667 712 02$aAkademii?a? nauk SSSR. 712 02$aNational Academy of Sciences (U.S.) 712 12$aUS-USSR Workshop on Planetary Sciences 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910957772303321 996 $aPlanetary sciences$94356027 997 $aUNINA
