Asteroids are the most abundant objects in the solar system. Hundreds of thousands of them are known at the present time, with more than a hundred added every day. Despite the large number of known asteroids, little is known about the physical characteristics of each individual. Many people only know the size. To other physical features such as shape, rotation time, direction of the axis of rotation and others you can only make a statement for a few objects.
Due to the irregular expansion of an asteroid and its rotation, the amount of sunlight reaching the viewer varies as a function of time. This change in brightness over time is referred to as the light curve. The shape of a light curve depends not only on the shape of the asteroid, but also on the viewing angle and the lighting. Collecting a sufficient number of these asteroid light curves can be used to create a physical model of the object using the light curve inversion method.
The aim of the project Asteroids@home is to increase the knowledge about the physical features of the asteroids. For this purpose, the photometric measurements of asteroids by professional and hobby astronomer takes using the light curve inversion method are processed into a 3D model with the rotation time and axis of rotation of the asteroid.
