Space Vocab😭 Flashcards
the path of an object in space as it moves around another object due to gravity
Orbit❣
the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.
Solar System💕
millions or billions of stars held together in a group by their own gravity
Galaxy🌌
Space and all of the space and energy in it
Universe🕋
an object that orbits a more massive object
Satellite⚙
a round pit left behind on a planet or other body of space left behind on a surface
Impact Crater💎
the straight line through all fixed points of a rotating rigid body around which all other points of the body move in circles
Axis of Rotation🎍
an instance of revolving
Revolution🕸
One part of the temperature changes other weather trends over the courses of a year
Season🎋
In an orbit a position and time in which sunlight shines equally on the Northern and Southern Hemispheres. A time of the year when daylight and darkness are nearly equal for most parts of earth.
Equinox🌫
In an orbit, a position and time during which one hemisphere receives its maximum area of sunlight while the other hemisphere receives its minimum amount. The time of the year when the days are either longest or shortest.
Solstice🏟
a large dark plain of solidified lava on the moon
Mare🗑
An event during which one object in space casts a shadow onto another
Eclipse🎆
The dark central region of a shadow such as the cone of complete shadow cast by an object
Umbra🏝
A region of lighter shadow that may surround a dark central region. The spreading cone of lighter shadow cast by an object
Penumbra☪
Average distance from the sun which is approximately 93,000,000 million kilometers
Astronomical unit❇️
An oval or flattened circle
Ellipse💯
A planet that has a rocky surface
Terrestrial Planet🔵
A large plane that consists
Gas Giant♨️
A small solid rocky body that orbits the sun
Asteroid🔴
a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun.
Comet⚫️
a small body of matter from outer space that enters the earth’s atmosphere, becoming incandescent as a result of friction and appearing as a streak of light
Meteor🌺
a meteor that survives its passage through the earth’s atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel.
Meteorite🌎
Earth centered theory of the solar system
Geocentric⭐️
A sun centered theory of the solar system
Heliocentric☄
The force that objects exert on one another because of their mass
Gravity🌪
The rise and fall of the ocean levels caused by the gravitational pull of the moon
Tide🌊
(of the moon between new and full) have a progressively larger part of its visible surface illuminated, increasing its apparent size.
Waxing ➡️
(of the moon) have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size
Waning ⬅️
a moon in between a half-moon but less than a full moon, or something that protrudes or creates an obvious bulge.
Gibbous Moon🌒🌓🌔
a thing that has has the shape of a single curve, especially one that is broad in the center and tapers to a point at each end.
Crescent Moon🌘🌒
the phase of the moon in which its whole disk is illuminated.
Full Moon🌕
the phase of the moon when it is in conjunction with the sun and invisible from earth, or shortly thereafter when it appears as a slender crescent
New Moon🌑
The moon is less than one-half illuminated by the sun but less than one quarter illuminated. Occurs when the moon’s illumination is increasing, First Quarter. The moon is one-half illuminated by the sun.
Quarter Moon🌓🌗
