"Here is the Sun at the Centre of the Solar System" " We are Zoomed into Mercury ... " " ... And Venus " " Now Let's Zoom Out " " Now We See The Earth... " " and The Moon " " The Earth and Moon Circle Each Other Closely " " And This Is Mars " " The Size of the Objects On Screen " " Is Not Dependent Upon Actual Body Size, But " " Depends Upon How Far Away They Are " " Now Speed Up The Display By Increasing The Step Time " "It Looks As If Venus Moves Close to the Path of The Earth" " But If We Change Orientation " " We Can See The Orbits Quite Clearly " " Now Let's Zoom Out Again and Change Orientation " " Here's Jupiter " " Display Can Be Switched From Tracks ... " " To Spots " " And Back to Tracks " " Change from Energy to Bodies " " Now The Earth Launches a Satellite " " We Need to Temporarily Decrease Step Time " " To Successfully Launch the Satellite " " Clear The Display " " Jupiter Swings The Satellite Out of Its Normal Orbit " " Saturn " " Thank You for Enduring This Demonstration "
