What are the dimensions of the Jupiter 2?

Answer 1

Since the fictional spaceship appeared as various full scale sets & models, it depends upon which Jupiter 2 you reference. Contemporary model kits & toys scale the Jupiter 2 out at 63' in diameter, & the depth of the hull 18' (this measurement excludes the bubble on top, & the fusion core beneath). These measurements are based upon Ron Gross's 1993 scale drawings & subsequent Polar Lights model kit based on his original.
