How to Create a Hanging Solar System Mobile
Foldable 3D Polyhedron Planetary Globes & Orbit Balance Mobile
What You Need Before Starting
Folding Instructions (5 Steps)
Follow each step in order. Press your folds firmly against the table using your thumbnail or a ruler for maximum performance.
Cut Out Planet Globe Nets
Cut out the colored planetary net strips: Giant Sun (Gold/Orange), Earth & Moon (Blue/Green), Jupiter (Striped), and Saturn (Yellow with wide ring).
Assemble 3D Planetary Polyhedron Spheres
Fold and glue each planet strip into a rounded 3D polyhedral globe, punching a tiny hole through the top pole for the hanging thread.
Fit Saturn’s Glorious Planetary Ring
Slide the paper ring over Saturn’s equator at a 20-degree tilt, securing it with two tiny dabs of glue on opposite sides.
Build the Horizontal Balance Crossbars
Tie strings from two wooden skewer balance arms. Hang the Sun and Jupiter on the first tier, and hang Earth, Moon, and Saturn on the second tier.
Hang from Ceiling & Watch the Planets Orbit!
Suspend the master center thread from your bedroom ceiling or lamp. Watch the planets gently rotate and orbit around each other in the room breeze!
Orbital Mechanics, Centre of Mass & Kinetic Mobile Balance
An Alexander Calder-style hanging mobile is a physical balance of torques (Torque = Force × Distance from Pivot). A heavier planet (like Jupiter) must hang closer to the center pivot, while a lighter planet (like Earth) can hang further out along the crossbar arm to maintain perfect gravitational horizontal equilibrium.
Air currents in the room gently spin each individual planet along its hanging thread, creating a mesmerizing dynamic simulation of our orbiting solar system.
Skills Your Child Develops with This Craft
Astronomy & Solar System Planetary Scale
Learning the order and characteristics of the planets (Gas giants, rocky planets, planetary rings).
Physical Center-of-Mass Balancing
Calibrating string pivot positions along balance arms to achieve horizontal suspension equilibrium.
3D Polyhedral Sphere Folding
Folding faceted multi-segment paper strips into rounded 3D planetary globes.
Fun Family Mini-Games to Play
Planetary Order Astronomy Quiz
Test yourself or a family member to name all the planets in order from the Sun outward (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune).
Glow-in-the-Dark Cosmic Night Display
Add tiny phosphorescent star cutouts hanging between the planets to turn your ceiling into a stunning 3D home planetarium.
Parent Note:
A handmade solar system mobile is a classic childhood bedroom treasure. Building it together fosters deep conversations about space exploration, the cosmos, and science.
