astronomy : science that talks about the space and the physical university
geocentric : describes the concepts of earth centered universe
orbit : spacecraft/path around stars, moon, planets
heliocentric : the view the sun at the center of the solar system
retrograde motion : westward position of the planets to the stars
ellipse : an oval
astronomical unit : average distance from earth to sun
rotation : the spinning of a body such as earth
revolution : the motion of body, as earth about the sun
precession : a slow motion of earth's axis that trace out a cone over a long period of time
perihelion : the point of an orbit of planet where it's the closest to the sun
aphelion : place in orbit of a planet where the planet is farthest from the sun
perigee : the point at which the moon is closest to earth
apogee : the point where the moon is furthest from earth
phases of the moon : the progression of changes in moon's appearance during the month
solar eclipse : when the moon moves in a line directly between earth and sun casting a shadow on earth
lunar eclipse : when the moon passes through earth's shadow
crater : depression at the summit of a volcano or which is produced by a meteorite impact
ray : any of system bright elongated streaks, sometimes associated with a crater on a moon
mare : smooth areas of the moon formerly thought to be seas
rille : long channel associated with lunar maria, similar to a valley or a trench
lunar regolith : a thin, gray layer on the surface on the moon
