In 2000, a team of astronomers (Nick N. Gorkavyi, Sara Heap, Leonid Ozernoy, Tanya A. Taidakova, and John Mather) announced that modelling of the asymmetric circumstellar disk infalling into Vega suggests that there may be a planet twice the mass of Jupiter at an orbital distance of about 50 to 60 AU from the star — up to one and a half times the «average» orbital distance of Pluto in the Solar System (N.N. Gorkavyi et al, 2000 and more discussion).
