[https://asteroidsathome.net/boinc/ '''''Asteroids@home'''''] is a '''''[[wikipedia:List_of_volunteer_computing_projects|volunteer distributed computing project]]''''' that needs your help to derive the shape and spin for a significant part of the asteroid population. The '''''[[wikipedia:Berkeley_Open_Infrastructure_for_Network_Computing|BOINC]]''''' application employs photometric measurements of asteroids from observed data. The results are asteroid convex shape models with the direction of the spin axis and the rotation period. The models are published in peer-reviewed journals and then made public in the [https://astro.troja.mff.cuni.cz/projects/asteroids3D '''''DAMIT'''''] database. Database of Asteroid Models from Inversion Techniques (DAMIT) is providing the astronomical community access to reliable and up-to-date physical models of asteroids - i.e., their shapes, rotation periods, and spin axis directions.

With a huge amount of photometric data coming from big all-sky surveys as well as from backyard astronomers, asteroid '''''[[wikipedia:Light_curve|Light curve inversion]]''''' modeling becomes viable. Light curve inversion is a mathematical technique used to model the surfaces of rotating objects from their brightness variations. However, data from surveys are often ''sparse in time'', which means that the rotation period - the basic physical parameter - cannot be estimated from the data easily. Contrary to classical light curves where the period is "visible" in the data, a wide interval of all possible periods has to be scanned densely when analyzing sparse data. This fact enormously enlarges the computational time and the only practical way to efficiently handle photometry of hundreds of thousands of asteroids is to use distributed computing. Moreover, the problem is ideal for parallelization - the period interval can be divided into smaller parts that are searched separately and then the results are joined together.[https://asteroidsathome.net/]

Since asteroids are remnants from the early solar system, studying them can provide insights into the processes that shaped our solar system's formation. They contain information about the building blocks of planets and can help us understand how planets like Earth formed and evolved.

Asteroids are diverse and offer a wide range of scientific and possibly economic opportunities. By studying their compositions, surface properties, and geology, scientists can learn more about the history and evolution of these small celestial bodies, as well as the broader processes that have shaped our solar system.
Asteroids are diverse and offer a wide range of scientific and possibly economic opportunities.

Some asteroids have the potential to impact Earth, and understanding their orbits, compositions, and sizes is crucial for developing strategies to mitigate potential threats. By studying asteroids, scientists can identify and assess impact hazards, and develop methods to deflect or mitigate threats.
