Only the largest features are labelled when a planet's disk appears very small to see more labels for smaller features, zoom in on the planet. Spacecraft that have landed on other solar system objects, and cities on Earth, are indicated with a green dot and label. With Surface Labels: Shows labels for named planetary surface features like craters, mountains, maria, and canyons. This option can slow performance when zoomed in a planet's disk, but generates a very pretty view. With Surfaces: Shows planet and moons with realistic surfaces (and ring systems) using NASA planetary mission image data.
COMET DATA FOR SKYCHART PLUS
Note: this option is only available in SkySafari Plus and Pro. To see these objects' surfaces unobscured by clouds, turn off this option. With Atmospheres: Shows the atmospheres of Venus, Earth, and Titan. When turned off, planets shown as fully illuminated, without any night side shading. With Phases: Shows planets and moons with their night sides shaded in a darker color.

Their north poles are drawn as bold lines south poles are shown with lighter lines. With Axes: Shows the rotational axes of planets and moons. The equator and prime meridian are drawn as bold lines other longitudes/latitudes are shown with lighter lines. Planet grids show the orientation of the planet's equator and rotational axis. With Grids: Shows planets and moons with surface coordinate grids. When turned off, most of the other settings in this section are disabled. Show Planets: Displays planets and moons in the sky chart. The settings in this view control the display of planets, moons, and other "minor bodies" in the solar system (asteroids and comets), as well as artificial Earth-orbiting satellites.
