| Planets are generally divided into two main types: rocky terrestrials and gas giants. |
| The most important insects vary with the season but the bulk of them are either mayflies, caddis, midges or terrestrials. |
| The Rose Center is a crystal cube, a machine in a garden, a welcoming space station for both terrestrials and aliens. |
| In the 1960's, for the first time in history, planet Earth was emerging in the consciousness of a global audience, terrestrials on a pale blue dot in the vastness of the skies. |
| Among the rocky terrestrials, the earth is located in the best place where living things can maintain their existence. |
| Gas giants are placed far from the sun, and rocky terrestrials like the earth are placed more closely to the sun. |
