| Mars | | belt of rock/mineral particles orbiting between Mars |
| RedGiant | | Kansas astronaut from Chapman, KS |
| Hubble | | closest planet to Sun; no atmosphere; no moons; erratic temperatures |
| Jupiter | | until 2008, was considered to be our ninth and outermost solar system planet |
| Aristarchus | | most accepted theory of beginning of universe from scientific evidence |
| Saturn | | day is longer than its year; no moons; thick, toxic atmosphere; evening "star" |
| Venus | | eclipse in which our Moon blocks our Sun's light from striking Earth |
| Pluto | | water discovered on surface; reddish soil; 2 moons; "Olympus Mons" |
| Luna | | only astronomical body supporting life as we know it; amazing, awesome! |
| Mercury | | known for extensive ring system; least dense of all planets; 24 known moons |

| Evans | | the galaxy to which we belong; estimated over 200 million stars in our galaxy |
| blackhole | | reaction initiates "birth" of star; fusion of hydrogen to helium; at least 10 million K |
| Halleys | | when asteroid chunk enters Earth's atmosphere and begins to "burn-up"; shooting star |
| Meteoroid | | acronym for National Aeronautic |
| Lunar | | source of many long-term comets; trillions of comets possible here |
| Meteor | | Pioneer in study of earth, moon, sun, and their interrelationships |
| MilkyWay | | its largest moon, Triton, has liquid nitrogen geysers; may have 11 moons |
| Hawley | | orbiting telescope deployed in 1990; source of many of our most prized images of space |
| Meteorite | | Greek/Latin name for our Moon |
| Neptune | | Most likely, the fate of our Sun in about 5 billion years from today |
| nova | | quasi-stellar radio sources; brightest objects in universe; remnants of "big bang"? |
| Mass | | most determining factor in prediction of star's "life-cycle"; original amount of matter |
| solarsystem | | Kansas astronaut from Topeka, KS |
| OortCloud | | chunk of asteroid material being attracted to Earth by gravity |
| Uranus | | eclipse in which the Earth blocks the Sun's light from striking our Moon |
| quasars | | First human to set foot on our Moon; 7-20-1969; Apollo 11 mission |
| Earth | | frigid cold; perturbations led to discovery of Neptune; 2X our distance from Sun |
| Asteroids | | larger than all other planets combined; gas giant; one day is only 10 hours! |
| KuiperBelt | | Pluto is the "king'. TNO's; many comets originate here; outside Neptune's orbit |
| BigBang | | means "new star" event; actually gigantic explosion which may repeat periodically |
