a star without a planet; it should be offset by planets freely floating in
space not gravitationally linked to a Solar system. In our Solar System alone;
we have 8 planets and various dwarf planets (Pluto) with many some of whom are still
waiting to be discovered proto-planets. The 1.6 ratio of planets to a sun is a
conservative estimate.
A Plenitude of Planets: Galactic Search Finds Exoplanets Are More Commonplace Than Stars
The ubiquity of extrasolar planets, and of relatively small worlds in particular, bodes well for searches for life-friendly Earth twins

The next time you look up at the night sky and find yourself marveling at the number of stars overhead, know that you are only seeing part of the magnificent bounty that our galaxy holds. Most of those Milky Way stars are not isolated orbs. Rather an average star has at least one planetary companion, invisible to the naked eye and in most cases as yet unseen by telescopes, according to a new analysis.
That extrasolar planets should be even more common than stars, which themselves seem innumerable, lends support to the hope that somewhere up in the night sky, circling one of those stars, is a world like Earth where life may have had a chance to take root, and maybe even have evolved into an intelligent form.
