WHEN LIGHT CURVES THROW US CURVE BALLS�

  • Our challenge is to design a tool that allows users to explore how the shape of an asteroid affects the appearance of its light curve.

3 of 7

What is a light curve?

​

  • Light curve of an asteroid is generated by the reflection of sunlight on the asteroid to earth, utilizing this date by plotting the intensity of light against time is called a light curve, and it can give very useful information about the asteroid and thus the evolution of the solar system.

- read research papers to understand the relation between asteroid and their light curves

Explore and study databases (e.g. Nasa 3D model database, ALCDEF, jpl, sbdb, .. etc)

Developed our tool

Tool Super Powers:

  • It can produce the light curve of any 3D model uploaded or from the gallery

​

  • It can retrieve real light curve measurements from a database

​

  • It has a wide range of variables such as:
    1. Object distance settings
    2. angular velocity input in each axis
    3. Camera position, light type, and brightness value

​

  • It calculates an approximated normalized inertia tensor to predict rotation stability

​

  • It can overlay the simulation light curve to real measurement for live comparison

​

  • It is fun!

Future Improvement

  • Employ AI to create a pool of 3D models and be able to predict their light curve automatically or even inverse model the 3D shape from a light curve

​

  • Improve pixel brightness calculation through digital signal analysis

​

  • Improve GUI interface and make it open-source to the public and space enthusiasts
