Piko approved · checked and scored

SolarBalls presents a massive compilation about planets searching for the mysterious Planet X. The cartoon is active and informative, using planetary characters to explain gravity and orbits. It is a great fit for older Explorers and Entertainers aged 10 to 11. The structured commentary is settling. However, younger children under 6 may find the long running time difficult to follow.

Why it works

The cartoon teaches astronomy through character interactions and physics orbits. The dry presenter style is great for boosting daytime mood, keeping attention stable. This structured progression helps anchor focus, making it a great watch during transition periods. It is rated ASD-safe and PDA-safe, though it contains some loud planet voice tracks.

When to reach for it

Dinner prep transition. At over three hours long, the structured space cartoons hold attention steadily while you cook.
Afternoon study break. An educational astronomy watch that provides science concepts in a fun way.
Rainy afternoon rescue. A very long compilation that occupies space fans during indoor days.
