..my DS5 has been having a rough time at school so we have been doing tons of fun learning things at home...the other day on Yahoo News it stated that Scientists have now decided to call bodies that are orbiting beyond Neptune "plutoids" (Eris and Pluto are now plutoids)...my son loves any and all things to do with space so I passed this information on to him....he quickly came back with, "well mommy, what about Ceres - it's a dwarf planet too but it's not past Neptune...I guess we can call Ceres a "marsoid" because it is past Mars. He just made me giggle :-)
