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
Gustav Holst the lower strings had to be replaced by a tuba to obtain an effective bass sound. With an anonymous string orchestra Holst recorded the "St Paul's Suite" and "Country Song" in 1925. Columbia's main rival, HMV, issued recordings of some of the same repertoire, with an unnamed orchestra conducted by Albert Coates.

In the early LP era little of Holst's music was available on disc. Only six of his works are listed in the 1955 issue of "The Record
