Patterns in Motion

5th grade CSA 4 Patterns in the Night Sky

QuestionAnswer
apparent brightness is a measure of the brightness of a star or other astronomical object observed from Earth
absolute brightness/magnitude allows astronomers to compare the brightness of stars as if they were all the distance of 10 parsecs from Earth. ... One parsec is equal to 3.26 light years
gravitational field amount of gravity present on a planet or moon; changes the amount of weight an object has
gravity a force that exists between any two objects that have mass; causes object to fall or be pulled to the center of the Earth
star distance from Earth the closer the star the bigger and brighter it appears; the farther away the smaller and dimmer it appears
shadows Whenever light is not able to go through an object, it creates a dark area around the object. This patch where the light can not reach is called a shadow.
rotation the spinning of a celestial body, such as a planet, around an axis
revolution the orbiting of an object around another object
axis an imaginary line that an object spins or revolves around
sundial a device that uses the position of the sun as it casts a shadow to measure time
constellations a particular area of the sky; a group of stars
Sun Earths closest star. Made of mostly helium and hydrogen. Appears bigger and brighter than other stars due to its closeness to the Earth.
why do constellations appear to move the constellations shift gradually to the west. This is caused by Earth’s orbit around our Sun. In the summer, viewers are looking in a different direction in space at night than they are during the winter.
The sun and stars ______________ to move across the sky, but really it is the Earths rotation and revolution to cause the sky to look different. appear
