came across (via presurfer) this nifty bit of nasa data noodling called the new worlds atlas. it’s a continuously updated database of all planets that have been discovered around stars other than the sun. you can zoom and rotate and move about the 3d map seeing where all of these extrasolar planets are in relation to us and each other in a heliocentric model with little ol’ sol in the center. good fun. they also offer a cool planet finding roadmap pdf among other goodies. check out the the extrasolar planets encyclopaedia for further info.
