Sorry for so many questions!

I have finished the skybox tutorial, and I am now wondering how to load in multiple models, and not have them affected by the camera object – this is surely done by changing the model matrix or something, but I’m not entirely sure how to implement in. Essentially, I have a main model that I want to be affected by the keyboard input, but these two other models I am loading in are to be static and unmoveable. How do I do this?

At the moment, this is the code within my while loop, discluding the clear colour set-up, etc. I want the planet and the probe to be immoveable. 

shader.Use();

        glm::mat4 view = camera.GetViewMatrix( );

        glUniformMatrix4fv( glGetUniformLocation( shader.Program, "projection" ), 1, GL_FALSE, glm::value_ptr(projection));

        glUniformMatrix4fv( glGetUniformLocation( shader.Program, "view" ), 1, GL_FALSE, glm::value_ptr(view));

        glm::mat4 model;

        model = glm::translate( model, glm::vec3( 0.0f, 0.0f, -5.0f ) ); //start slightly below origin

        //model = glm::translate( model, glm::vec3( 0.0f, (GLfloat)glfwGetTime() * 0.75f, 0.0f ) ); // moves itself up slowly

        //model = glm::rotate( model, (GLfloat)glfwGetTime() * -0.5f, glm::vec3(0.0f, 1.0f, 0.0f) ); // spins

        glUniformMatrix4fv( glGetUniformLocation( shader.Program, "model" ), 1, GL_FALSE, glm::value_ptr(model));

        ship.Draw(shader);

        model = glm::translate(model, glm::vec3(-5.0f, 10.0f, -10.0f ));

        model = glm::scale(model, glm::vec3(0.2f, 0.2f, 0.2f));

        glUniformMatrix4fv(glGetUniformLocation(shader.Program, "model"), 1, GL_FALSE, glm::value_ptr(model));

        probe.Draw(shader);

        model = glm::translate(model, glm::vec3(105.0f, 10.0f, -5.0f ));

        model = glm::scale(model, glm::vec3(1.5f, 1.5f, 1.5f));

        glUniformMatrix4fv(glGetUniformLocation(shader.Program, "model"), 1, GL_FALSE, glm::value_ptr(model));

        planet.Draw(shader);

        glDepthFunc(GL_LEQUAL);

        skyboxShader.Use();

        view = glm::mat4(glm::mat3(camera.GetViewMatrix()));

        glUniformMatrix4fv(glGetUniformLocation(skyboxShader.Program, "view"), 1, GL_FALSE, glm::value_ptr(view));

        glUniformMatrix4fv(glGetUniformLocation(skyboxShader.Program, "projection"), 1, GL_FALSE, glm::value_ptr(projection));

        glBindVertexArray(sbVAO);

        glBindTexture(GL_TEXTURE_CUBE_MAP, skyboxTex);

        glDrawArrays(GL_TRIANGLES, 0, 36);

        glBindVertexArray(0);

        glDepthFunc(GL_LESS);

        glfwSwapBuffers(window);

Thanks in advance.
