Weather is clouds, storms, rain and lightning; plants stand and animals roam on habitable planets in low orbit (both off by default on phones), and rocks lie on solid ground near the UFO. Turn them off if the game runs slowly. Wireframe draws the planets, moons and ship as their triangles (turn Weather off to see under the clouds). Freeze view (F) keeps what's drawn as it was for the camera then, and outlines what that camera saw, while you turn and zoom the camera to look at it from outside. Third-person view (C) draws the whole planet, system or galaxy from a camera of its own, showing what the game's camera draws and culls and where that camera is and looks; drag and zoom to look round, and V (or the button at the top) hands the drag back to the game's camera. Clicking a planet or the ground in it flies there as usual.
Planet lab
Build any planet or moon, change everything about it and look at it up close.
