--- tags: lookbooks --- # prototype-hh-juliana-animation Juliana is a PhD candidate in Astrophysics. Her presentation includes animations of a planet orbiting a star. The animation we're looking for is largely pretty simple. It is meant to illustrate the level of light that is being dimmed as a planet passes in front of a star, as well as a graphical readout of the light levels that are being measured [you can find the original version here](https://exoplanets.nasa.gov/alien-worlds/ways-to-find-a-planet/#/2) ![Juliana's research, Harvard Horizons 2022--this visualization is from NASA](https://files.slack.com/files-pri/T0HTW3H0V-F03109STVTQ/screen_shot_2022-02-01_at_4.39.50_pm.png?pub_secret=1e25d3b600) ## the approach there are a couple ways to do this, you can make the star yourself, or pull a premade one from [Sketchfab](https://sketchfab.com/), [CGTrader](https://www.cgtrader.com/), or [TurboSquid](https://www.turbosquid.com/) and then finally, you'll need to rig both a camera, and your alien planet into a circluar animation -- this process will be extremely similar <div class="sketchfab-embed-wrapper"> <iframe title="The Sun" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen; xr-spatial-tracking" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered web-share src="https://sketchfab.com/models/0d28aa65eb174d948c2716d73e8fd3bd/embed"> </iframe> <p style="font-size: 13px; font-weight: normal; margin: 5px; color: #4A4A4A;"> <a href="https://sketchfab.com/3d-models/the-sun-0d28aa65eb174d948c2716d73e8fd3bd?utm_medium=embed&utm_campaign=share-popup&utm_content=0d28aa65eb174d948c2716d73e8fd3bd" target="_blank" style="font-weight: bold; color: #1CAAD9;"> </p></div> <iframe width="640" height="360" src="https://www.youtube.com/embed/2pLYyn86qQU" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> <iframe width="640" height="360" src="https://www.youtube.com/embed/63_nvGRHLIQ" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
