The Chart of the Solar System is to scale by default, but if you zoom in towards planets (which just makes the planets bigger, not the distance between the planets), they will no longer be to scale. For that chart, use arrow keys; left and right to go between planets (red dot on bottom indicates location; left is towards the Sun, right is towards Neptune), and use up and down to zoom in or out. ...So if you can't see the tiny rocky planets, then use the up arrow key to zoom in. Additionally, you can hover the mouse over the planets in order to reveal little information boxes (and if you click on Earth, you get to go to information boxes on: Moon Phases, Seasons Explanations, and Planned Space Telescope Location. On the info pages, use the left and right arrow keys to move between the slides. Problems: In the Solar System Chart, there is a maximum limit to how big objects in Scratch can get, so at a certain point, celestial objects will no longer get bigger. Additionally, the Sun can sometimes engulf Mercury if it gets to large, so if you want to see Mercury, make sure it is towards the left side of the screen. And if you see anything weird here, it may be because this was a school project from a while back (that I re-edited)
