Drag to pan. Use the mouse wheel to zoom. Hover over a star to get a quick overview of the planets and moons in the star system.
There is one row per planet/moon. Every row stars with an icon which roughly depicts the planet's size and color, and if it's a moon the icon is off centered. Then a three digit figure describes the planetary environment - thermal, weather and tectonic hazards. Then is the total mineral value of the planet, followed by the value per unit of volume, or '+' for non-signle digit values. And the final figure shows the total amount of bio data for the planet.
