	Since [[wikipedia:Asteroid\|'''''asteroids''''']] are remnants from the early solar system, studying them can provide insights into our solar system. 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. Additionally, 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 these impact hazards, and develop methods to deflect or mitigate threats.

	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 — though it generally has been far too compute intensive for use at scale.

	Light curve inversion is a mathematical technique used to model the surfaces of rotating objects from their brightness variations. However, data from the surveys which serve as input data 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.
