A String, a Globe, and the Moon's Real Distance
Professor Anu Ojha at The Royal Institution uses a string wrapped around a globe to visualize the Moon’s distance—about 10 Earth circumferences away—making the vast scale more intuitive than numbers alone. The demonstration puts the Earth‑Moon gap in perspective against the ISS’s 400 km orbit and notes that Venus would be even farther, highlighting the challenges of interplanetary travel and tying the lesson to Artemis II’s Moon flyby.
