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
Solar power in Australia the state government announced a new round of finance for renewable energy projects which included a Planet Arc Power - Schneider Electric development of a $13.9m solar PV and battery project at a major distribution centre in Adelaide’s North. The project includes a micro-grid management system optimising 5.7MW of solar PV coupled with 2.9MWh of battery storage. The University of South Australia will develop 1.8MW of ground and roof mounted solar PV at its Mawson Lakes campus. At the Heathgate Resources Beverley mine there are plans for a relocatable 1MW of solar PV paired with a 1MW/0.5MWh battery which will
