This 3D solar system model lets future astronombers move the eight planets around the sun so they get a perspective of their relative orbits. And they can refer to the bonus wall chart for fun facts. The planetarium model in this super cool science kit easily snaps together, no glue needed, and kids can paint and highlight it to create the glow effects. Then watch it glow-in-the-dark and imagine you're out in space looking down on the amazing solar system. This educational toy is a total blast!
