Hi ilan, I wanted to say I big thank you for sharing your code. My daughter(12) and I (44) have been learning B4X together an hour per week (the last few months) and today we had fun with your solar code. She particularly loved changing the randomness of the star sizes and experiments with forward and reverse speeds! We also had a conversation about adding the moon and even the ISS.
Next week we will try the correct values of distance to the sun and see how big the canvas has to be to fit it all on.
