1Space: The Big Picture Chap 1; Lesson 1.1 T.O.C:Space in Perspective
2Arrangement of (known) Universe Earth (8,000 miles in diameter)Solar system(w.w)- the Sun (a star) and all the planets that orbit around itMilky Way Galaxy (the galaxy we live in)Galaxy(w.w)- large system of stars & space objects held together by mutual gravitation (separate from other galaxies due to lots of space in between)Universe(w.w)- all of space/cosmos and everything in it.
3Objects in Space Orbit!Orbit(w.w)- path one object takes around another.Caused by the influence of gravity.Can you name some space objects that orbit something?Moon orbits EarthEarth/planets orbit the SunSpace telescopes/satellites also orbit
4The Sky Seems to Turn as Earth Rotates It doesn’t though. Earth is just moving.Apparent mvmt led early astronomers to believe Earth was the center of the universePart of view of night sky is blocked by EarthThe moon is our closest neighborConstellations/stars change position in sky as Earth rotatesConstellation(w.w)- various groupings of stars that have been given names/stories & appear to make shapes.Stars are always moving, but we’re so far away we can’t tell.Polaris- located directly above N. pole (can tell Earth is rotating from here)Used by sailors/navigators/ppl to figure out location/directionConstellation Activity
