Auguste Honoré Charlois (French pronunciation: [oɡyst ɔnɔʁe ʃaʁlwa]; November 26, 1864 – March 26, 1910) was a French astronomer who discovered 99 asteroids while working at the Nice Observatory in southeastern France.

[7] Although he started searching for asteroids in the era of visual detection, by 1891 Max Wolf had pioneered the use of astrophotography to drastically speed up the rate of detection of asteroids, and both Wolf and Charlois separately discovered far more asteroids than would have been feasible by visual detection.

[4] In 1899, Charlois received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society, and was also awarded the Valz Prize by the French Academy of Sciences in 1889 for his work on calculating asteroid orbits.

The man was found guilty and given a life sentence of hard labor in New Caledonia.

[9] The asteroid 1510 Charlois, discovered by André Patry at Nice Observatory in 1939, was named in his honour.
