List Of Multiplanetary Systems
There are (as of November 27, 2012) 126 known multiplanetary systems (i.e. stars with at least two confirmed planets), beyond our Solar System. The star table below contains information about the coordinates, spectral and physical properties, and number of confirmed planets (as of July 7, 2011). The two most important stellar properties are mass and metallicity because it determines how these planetary systems form. The higher mass and metallicity tend to have more planets and more massive planets.
There are 65 stars with two confirmed planets, 18 with three, 5 with four, 3 with five, 1 with six, 1 with seven, and 1 with eight. The star with the most confirmed planets is our Sun, which contains 8 confirmed planets. The star with the most confirmed exoplanets is HD 10180 with 7 planets.

Famous quotes containing the words list of, list and/or systems:
“Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.”
—Janet Frame (b. 1924)
“All is possible,
Who so list believe;
Trust therefore first, and after preve,
As men wed ladies by license and leave,
All is possible.”
—Sir Thomas Wyatt (1503?–1542)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
