Currently, astrometric solving is exclusively done by software programs. The program extracts the star x,y positions from the celestial image, groups them in three-star triangles or four-star quads. Then it calculates for each group a geometric hash code based on the distance and/or angles between the stars in the group.

MPC's astrometric database contains more than 200 millions entries, split up into 199.9 million minor-planet observations as well as 0.4 million comet- and 0.6 million satellite-observations. [1] The ceremonial first entry, by date, is the discovery observation of Ceres made by G. Piazzi on 1 January 1801.
In April 2021, the developers announced plans to launch a Kickstarter project later in the month to turn the demo into a full game. [12] On April 18, a Kickstarter project for the full version of the game was released under the name Friday Night Funkin': The Full Ass Game and reached its goal of $60,000 within hours. [17]
The Bonner Durchmusterung (abbreviated BD), was initiated by Friedrich Argelander and using observations largely carried out by his assistants, which resulted in a catalogue of the positions and apparent magnitudes of 342,198 stars down to approximate apparent magnitude 9.5 and covering the sky from 90°N to 2°S declination.
