Auguste Charlois
Auguste Honoré Charlois (November 26, 1864 – March 26, 1910) was a French astronomer who discovered 99 asteroids while working at the Nice Observatory in southeastern France. Asteroid Discovery His first discovery was the asteroid 267 Tirza in 1887. He photographed 433 Eros on the very night of its discovery by Gustav Witt, but was not able to act quickly enough before Witt announced his find. 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. 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.

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

1510 Charlois
1510 Charlois, provisional designation , is a carbonaceous Eunomia asteroid from the middle region of the asteroid belt, approximately 24 kilometers in diameter. It was discovered on 22 February 1939, by French astronomer André Patry at Nice Observatory in southeastern France, and later named after astronomer Auguste Charlois. Orbit and classification ''Charlois'' is a carbonaceous C-type asteroid and a member of the Eunomia family, a large group of otherwise mostly S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central main-belt at a distance of 2.3–3.1 AU once every 4 years and 4 months (1,595 days). Its orbit has an eccentricity of 0.15 and an inclination of 12 ° with respect to the ecliptic. As no precoveries were taken and no prior identifications were made, the body's observation arc begins with its discovery observation in 1939.

298 Baptistina
Baptistina (minor planet designation: 298 Baptistina) is an asteroid orbiting in the asteroid belt. It is the namesake of the Baptistina family. It was discovered on 9 September 1890 by Auguste Charlois of Nice. The source of its name is unknown. It measures about in diameter. Although it has an orbit similar to the Flora family asteroids, Baptistina is an unrelated interloper.M. Florczak et al.

293 Brasilia
Brasilia (minor planet designation: 293 Brasilia) is a large Main belt asteroid that was discovered by French astronomer Auguste Charlois on 20 May 1890 in Nice. It is the namesake of the Brasilia family, a smaller asteroid family of X-type asteroids in the outer main-belt. However, ''Brasilia'' is a suspected interloper in its own family.
