The Solar System in Scale with The Royal Institution #shorts #space #science #solarsystem

The video by the Royal Institution uses a 5‑centimetre sphere called Clementine to represent the Sun, then walks through a London theater and street to place the planets at true‑to‑scale distances, revealing how conventional textbook diagrams compress the solar system. At this scale Mercury sits roughly two metres from the Sun, Venus three‑point‑eight metres, Earth five‑point‑four metres and Mars eight‑point‑two metres. The asteroid belt follows, and the model forces the presenter to leave the building to locate Jupiter at twenty‑eight metres, Saturn at fifty‑one‑point‑five metres, Uranus one‑hundred‑three metres and Neptune one‑hundred‑sixty‑two metres away. The narrator notes that if planetary diameters were also scaled, Mercury would shrink to a 0.17‑mm grain of sand, essentially invisible, underscoring that distance, not size, dominates perception. He also references Voyager 2’s twelve‑year journey to Neptune, equating the 162‑metre model gap to 4.5 billion kilometres in reality. By translating astronomical distances into walkable lengths, the demonstration makes the vastness of the solar system tangible for audiences, reinforcing the need for perspective in education and inspiring curiosity about space exploration.
