STAR UNIT FLASH BACKS 2013 M0NDAY, JAN. 28 WEEK 4 1. TRUE OR FALSE: If a star is colored red, that means that it is moving AWAY from us (due to Red Shift). 2. How long would it take for an F-22 Raptor jet flying at top speed (1,500 miles per hour) to fly from the earth to the sun? a.) 8 minutes b.) 1 year c.) 7 years 1. TRUE OR FALSE: The Andromeda Galaxy will most likely eat our Milky Way Galaxy in about 4 billion years. M0NDAY, JAN. 28 WEEK 4 1. TRUE OR FALSE: If a star is colored red, that means that it is moving AWAY from us (due to Red Shift). Only the spectrum of the star would shift—need a special instrument to look at spectrum (spectroscope) 2. How long would it take for an F-22 Raptor jet flying at top speed (1,500 miles per hour) to fly from the earth to the sun? a.) 8 minutes b.) 1 year c.) 7 years 1. TRUE OR FALSE: The Andromeda Galaxy will most likely eat (aka combine with) our Milky Way Galaxy in about 4 billion years. Tuesday, Jan. 29 1. TRUE OR FALSE: A star’s color corresponds to its temperature. 2. How many earth’s would fit inside the volume of the sun? a.) 1 billion b.) 1 million c.) 1, 000 3. TRUE OR FALSE: It would take 1,100 years to fly (airplane) around the largest known star. Tuesday, Jan. 29 1. TRUE OR FALSE: A star’s color corresponds to its temperature. 2.
