The modelling suggested that a Neptune - like planet actually formed much closer to Vega and was pushed by a Jupiter - like planet in an inner orbit out to its current wide orbit around 80 AUs away from Vega over about 56 million years, sweeping many comets out with it and causing the dust disk to become clumpy (Mark C. Wyatt, 2003).
