This data visualization is generated from real daily asteroid data. Each upper circle, in the graphic, represents an individual asteroid and its size relative to the other asteroids. The distance from the earth is represented by the space between the bottom of each circle and the blue space on the bottom. These beautiful visualizations are generated from a script using the open data sources provided by NASA Asteroids – NeoWs at https://data.nasa.gov/Space-Science/Asteroids-NeoWs-API/73uw-d9i8
