ASTR 1101 : ASTR 1101 Review 1
Document Summary
Exam review day: all multiple choice, he gives us scantron, need calculator and pencil, class, tutorials, videos, and stories are all fair game. If he didn"t talk about it it: 40 questions, read important concepts on study guide posted on moodle, doppler effect: keys to cosmos wont be on test, red shift- light shifted towards red. Bigger, away from you redder: smaller, towards you, compressed bluer, philae lander: was on rosetta, supposed to detach and land on comet but bounced 3 times and is lost now. Summer is tipped towards the sun and winter is tipped away from the sun. masses: brighter and bluer. P^2=a^3 (period of orbit in years squared is equal to the distance from the sin cubed) Something in motion stays in motion blah blah: all orbits are ellipses. Ii: scientific method, units, phases of the moon. New moon (rises on the same side as the sun) Total eclipse of moon only at full moon.
