It's spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in it's core. Since more powerful stars use their fusion fuel more quickly than smaller ones, Vega's life time is only one billions years, a tenth of our Sun's ten billion years. Vega is two and a half times more massive than our Sun and burns at fifty times the power.
Vega has a disk of dust and gas around it, discovered by the IRAS satellite in the mid 80's. This either signifies planets or planets that may soon form. The protoplanetary disk is, as can be guessed from it's name, believed to be a precursor to the formation of planets but it can persist long after planets have been formed if there are no giant planets such as [Jupiter|Jupiter].
