Another Lego sphere tryout – an octahedron made of triangles. The triangles are made from 3 1x6 plates connected by "in-plane" hinges. The triangles are then connected to each other with "out-of-plane" hinges. I realized the sides could be decorated with the same in-plane hinges which gave the thing a nice bit of texture 😊

For #spacetober_challenge day 29 prompt orbit: #mathematician and #astronomer Johannes Kepler (1571-1630)! We remember him for his role in the Scientific Revolution, and his three laws of planetary motion in particular. His laws modified Copernicus’ heliocentric model; he replaced the circular orbits with elliptical ones & described velocities of planets. Today we know them as:
