Earth and Solar System

Kbase Thing

The Solar System is the region of the universe near the sun that includes the sun, the eight known major planets and their moons or satellites, and objects such as asteroids and comets that travel in independent orbits. Cyc also knows about planetary systems in general, any group of celestial bodies moving in orbit around a central star or stars, so the Solar System is a specific planetary system which includes the earth’s sun. Cyc knows the difference between earth, the soil, and Earth, the planet.
