Make all the tests below pass to complete the project. Be sure to get creative, and have fun!\n\n**Don't forget to connect to your database after you create it** :smile:\n\nHere's some ideas for other column and table names: `description`, `has_life`, `is_spherical`, `age_in_millions_of_years`, `planet_types`, `galaxy_types`, `distance_from_earth`.\n\n**Notes:**\nIf you leave your virtual machine, your database may not be saved. You can make a dump of it by entering `pg_dump -cC --inserts -U freecodecamp universe > universe.sql` in a bash terminal (not the psql one). It will save the commands to rebuild your database in `universe.sql`. The file will be located where the command was entered. If it's anything inside the `project` folder, the file will be saved in the VM. You can rebuild the database by entering `psql -U postgres < universe.sql` in a terminal where the `.sql` file is.\n\nIf you are saving your progress on freeCodeCamp.org, after getting all the tests to pass, follow the instructions above to save a dump of your database. Save the `universe.sql` file in a public repository and submit the URL to it on freeCodeCamp.org.",
