Asterank is an asteroid database maintained by Ian Webster, an engineer at Google. It contains information for over 600,000 asteroids.
Scientists know very little about the composition of asteroids. Most data used in our calculations come from the JPL’s Small Body Database and the Minor Planet Center. The overwhelming majority of asteroids have no spectral classification and are missing other important data attributes. Without full information it is impossible to fully estimate the true value of an asteroid or the cost of mining it.
Asterank applies accurate, up-to-date information from world markets and scientific papers. To ensure realistic estimates, data from meteorities on Earth and known reference asteroids heavily influence our calculations.
