Telescope Lander/Rover Orbiter/Probe An device used to detect EM waves reflected or given off by objects in space Spaceship Earth planet moon satellites gravity orbit Sun stars constellation meteor comet Solar System galaxy Milky Way Universe ellipse Where asteroids orbit the sun (between mars and Jupiter A manned or unmanned vehicle that can land and or move about on a planet An unmanned spacecraft that orbits an object in space. A probe plunges into the planet A manned or unmanned ship that goes into space Our home planet A round object that has cleared its orbit of all other objects A smaller body that orbits a planet An object (natural or man-made) that orbits a larger object A force determined by mass. The greater the mass, the greater the gravity The pathway a satellite takes around another object Our local star Gas objects that convert hydrogen into helium using fusion Stars that form a pattern in the night sky A hunk of metal that enters our atmosphere A hunk of ice and gas that forms a long gassy tail as it orbits the sun Our sun, planets, moons asteroids, and comets A group of billions of stars held together by gravity The name our universe that we live in Everything The oval shape (like a flattened circle) of most orbits in space Axis of Rotation The imaginary line running through the center of the Earth Rotation Revolution Seasons Solstice Equinox Eclipse Solar Eclipse Lunar Eclipse Moon Phases To spin To go around or orbit Changes of weather patterns due to Earth’s 23 degree axis tilt When the sun shines mostly on either the northern or southern hemisphere When the sun shines equally on Northern & Southern Hemispheres Shadows in space that happens when the earth, mon, and sun are in a line The moon’s shadow falls upon the earth…Earth, moon, sun The earth’s shadow falls upon the moon…moon, Earth, sun Waning The pattern of how the moon looks different each night, caused by the changing positions of the earth, mon, and sun When the lighted porting of the moon is getting smaller Waxing When the lighted porting of the moon is getting larger Waning Crescent Waxing Crescent Waning Gibbous Waxing Gibbous Full Moon New Moon Tides Inner Planets Outer Planets gravity Terrestrial Gas Giants Pattern of high and low tides caused by the moon and sun’s gravity pull on our oceans Planets inside the asteroid belt (terrestrial) Planets outside the asteroid belt (gas) A force determined by mass that holds objects in orbit Planets made of land (inner planets) Mercury, Venus, Earth, Mars Planets made of gas (outer planets) Jupiter, Saturn, Uranus, Neptune Vocabulary: SPACE
