Solar System 7 light-years away. Compared to many other planetary systems, the Solar System stands out in lacking planets interior to the orbit of Mercury. The known Solar System also lacks super-Earths (Planet Nine could be a super-Earth beyond the known Solar System). Uncommonly, it has only small rocky planets and large gas giants; elsewhere planets of intermediate size are typical—both rocky and gas—so there is no "gap" as seen between the size of Earth and of Neptune (with a radius 3.8 times as large). Also, these super-Earths have closer orbits than Mercury. This led to hypothesis that all planetary systems start
Suite (music) dexterity from the pianist. Arnold Schoenberg's first use of the twelve-tone technique throughout an entire work was in his Suite for Piano, op. 25. Modeled on the Baroque keyboard suite, the piece consists of six movements entitled "Präludium" (Prelude), "Gavotte", "Musette", "Intermezzo", "Menuett" (Minuet, with Trio), and "Gigue".
