A Visit to the Planetarium is the second half of the thirteenth episode of Ready Jet Go!.
Sean and Sydney take Jet to the DSA to see a show at the Planetarium. But things take a fun turn when Jet decides to upgrade the show with some Bortronian technology and sings a song explaining how to find Earth in the Milky Way galaxy!
Our sun is actually a bright star out on a spiral arm of the Milky Way Galaxy, which is made of billions of other stars, and our galaxy is just one of billions of galaxies.
- At the booth, there is a man named Don, who may actually be Dr. Bergs. He has a silhouette similar to Bergs', and he is voiced by Brian Drummond, just like Bergs.
- Jet mentions Bortron to Earthie children in his song, but he does not say that he is from Bortron 7.
- The film shown at the planetarium was most likely made before Pluto's demotion in 2006, since it was included as part of the show.
