It would have to be 100 times as massive as it is, which means its gravitational effects on the planets in the solar system would be 100 times stronger. The orbits of the planets would be very different, and probably NONE of them except possibly Mercury, Neptune and Pluto, would remain substantially unchanged. Mars would probably be ejected from the solar system as would Saturn. The other planets would have complex loop-de-loop orbits which would probably not be stable over millions of years.
