This is a solar system simulator. When you press the green flag, you should start seeing the title screen fade and the planets revolve around the sun. Hovering your mouse over any planet causes it to show and speak it's name. Clicking on any planet will show it's details. Clicking on the home button will take you back. The above works for the sun as well. Also Venus rotation is not wrong, it is like that in the real life too. See if you can find the Easter egg. If you liked it, check this one out: https://scratch.mit.edu/projects/597011820 Pssstttt...... Since you cared to scroll down here, I'll let you know a little secret. Press B on your keyboard (if you're on a computer obviously) and see the magic. Also the sun will become a neutron star, not a black hole at the end of it's life. Black holes are just more interesting.
