The Vega system may be somewhat like a scaled-up version of our own solar system, as shown in this diagram. Astronomers have discovered a band of warm dust close to the star, and a band of colder material farther out. Planets may inhabit the space between them. The solar system is shown both to scale (bottom) and enlarged to the same size as the Vega system. [NASA/JPL/Caltech]
