| 1. | This relation between the Sun and planetary motion is not an odd and inexplicable coincidence. | |
| 2. | What effects would planetary alignment have? | |
| 3. | Time was running out for the Earthlings as their planetary environment was in decay. Space travel became a necessity. | |
| 4. | The epicycle made it possible for the Greeks to explain the planetary movements. | |
| 5. | The surface of Mercury has been shaped by three processes: impact cratering where large objects struck the surface resulting in crater formation, volcanism where lava flooded the surface, and tectonic activity where the planet's crust moved in order to adjust to the planetary cooling and contracting. | |
| 6. | While still an undergraduate, Adams performed an investigation to try to explain the reason for the irregularities in the motion of the planet Uranus. He theorized that the unexpected planetary orbit could be due to the presence of an as yet undiscovered planet. | |
| 7. | In 1600, Tycho Brahe hired Johannes Kepler as his assistant. In later years, Kepler would use Brahe's work as the basis for the laws of planetary movement which he developed. | |

| 11. | Oceanic and atmospheric Rossby waves — also known as planetary waves — naturally occur largely due to the Earth's rotation. These waves affect the planet's weather and climate. | |
| 12. | Rossby waves, also known as planetary waves, naturally occur in rotating fluids. Within the Earth's ocean and atmosphere, these waves form as a result of the rotation of the planet. | |
| 13. | "We don’t have any rocks on Earth that are older than about 4 billion years old, so we don’t know exactly how much volcanic activity there was or how heavily Earth was bombarded by asteroids” said Barbara Cohen, a planetary scientist who heads Goddard’s Mid-Atlantic Noble Gas Research Laboratory. | |

| 16. | Interstellar, as opposed to interplanetary, travel was quite impossible until the advent of sub-atomic power. Fortunately this source of power was seldom gained until late in a world's development, when mentality was mature enough to wield this most dangerous of all physical instruments without inevitable disaster. Disasters, however, did occur. Several worlds were accidentally blown to pieces. In others civilization was temporarily destroyed. Sooner or later, however, most of the minded worlds tamed this formidable djin, and set it to work upon a titanic scale, not only in industry, but in such great enterprises as the alteration of planetary orbits for the improvement of climate. This dangerous and delicate process was effected by firing a gigantic sub-atomic rocket-apparatus at such times and places that the recoil would gradually accumulate to divert the planet's course in the desired direction. | |
| 17. | The Mars 2020 Perseverance rover will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary mission to collect and cache Martian rock and regolith. | |
