**A science communicator is demonstrating the concept of multiples using planetary orbits. If one planet completes an orbit every 28 days and another every 42 days, after how many days will both planets align at their starting positions again?** Scientists and space enthusiasts aren’t the only ones turning heads online—these orbital mechanics puzzles have quietly gained traction in science education circles. The question about planetary alignment using 28- and 42-day orbital cycles connects basic math with fascinating real-world examples, sparking curiosity about how celestial patterns work beyond Earth. **Why This Question Is Trending in the US** Right now, planetary orbits and periodicity are resonating across digital platforms, especially among curious learners searching for digestible science content. The rising popularity of astronomy education—fueled by social media explainer videos, interactive apps, and teacher-led STEM initiatives—has made questions about orbital resonance increasingly relevant. People aren’t just asking *if* planets align; they want to understand *when* and *why* this timing matters in broader astronomical contexts.
