Audio 3D clip for music in tree.js

During my lessons I had to make a 3D clip for a music in tree.js . I chose to reproduce the movement of the planets around the sun. The moon revolves around the earth. A heart rotates in the background. The stars and the sun are fixed. The speeds and distances are approximately proportional to reality. The size of the planets is not at all proportional to reality.  The movements are to the rhythm of the music. The lyrics of the song are displayed on the sun via the .lrc file of the chosen song. The frequentation of the music is displayed below .
