I finished one animation about the solar system.
The order that you present the planets seems strange.
Nice job, educational for me to look at those visual comparisons, I like the sun at the end, very dramatic. I would lower the spec value on the earth though, it makes it look small. And set it to music.
Maybe present some statistics along with the visuals? Just an idea, really. I’m sure you had some sort of data to scale the planets! 
excellent. My only crit would be to have added the name of the planets so kid can learn from your video. Even adults too…as Render10 said kind of statistic or numerical proportions would be great. I got some music tracks great for this. Music would entertain even more.
Great work 5/5

neat. maybe you could also add a conclusion at the end? something like “Pretty small.”
