Space Flashcards
Satellite
Impact crater
Axis of rotation
Revolution
An object that orbits more massive objects
A round pit left behind on the surface of a planet after a smaller object strikes the surface
An imaginary line about which a turning body,such as earth rotates
The time it takes an object to go around once of
Orbit
Solar System
Galaxy
Universe
The path of an object in space as it moves around due to gravity
The sun and its family of moons,planets and other objects
Millions or billions of starts held together by their own gravity
Space and all the matter and energy in it
Season
Equinox
Solstice
mare
One part of a pattern of temperature changes and other weather trends over the course of a year
In an orbit position of time in sunlight shines equally on the northern hemisphere and the Southern Hemisphere
A dark large plain of solidified lava on the moon
The time of year when days are either shortest or longest
Eclipse
Umbra
Penumbra
Astronomical unit
An ovel or flattened circle
The dark central region of a shadow
The region of a lighter shadow that may surround an umbra
Earths average distance from the sun
Ellipse
Terrestrial planet
Gas giant
Asteroid
An event during which one object in space casts a shadow onto another
Earth or a planet similar to earth the has a rocky surface
A small solid rocky body that orbits the sun
Matter with no definite volume or definite shape
Comet
Meteor
Meteorite
Gravity

A small object from outer space that passes through earths atmosphere and reaches the surface
The force that objects exert on each other because of their mass
Tide
Waxing
Waning
Gibbous Moon
The alternate rising of the sea
The moon at any time after a new moon or a full moon
When a smaller part is the moon is illuminated
When the moon has an observable part greater then a semicircle but less then a circle
Crescent Moon
Full Moon
New Moon
Quarter Moon
Part way between a half moon and a new moon
The phase of a moon and which its whole disc is illuminated
When the moon and the sun’s conjunction is invisible from Earth
When the moon is half illuminated from the sun
