In 1997 a planet of roughly Jupiter's mass was discovered in orbit around the star Andromedae. Two more have now been identified, providing the first example of a solar system other than our own containing more than one planet.

Analysis of the Hipparcos Measurements of υ Andromedae: A Mass Estimate of Its Outermost Known Planetary Companion
We present an analysis of Hipparcos astrometric measurements of υ Andromedae, a nearby main-sequence star around which three planet candidates have recently been discovered by means of radialExpand
Astrophysics in 1999
The year 1999 saw the arrival of a star with three planets, a universe with three parameters, and a solar corona that could be heated at least three ways. In addition, there were at least threeExpand
Extra-solar planets
The discovery of the first extra-solar planet surrounding a main-sequence star was announced in 1995, based on very precise radial velocity (Doppler) measurements. A total of 34 such planets wereExpand
Stability and chaos in the υ Andromedae planetary system
The detection of three planets orbiting the star ? Andromedae marks the first discovery of a multiple-planet extrasolar system associated with a main-sequence star (Butler et al. 1999). The unusualExpand
Stability Analysis of the Planetary System Orbiting υ Andromedae
We present numerical orbital integrations designed to test the stability of the three planets detected in orbit around υ Andromedae and possible smaller bodies orbiting in the system which have notExpand
