12373 Lancearmstrong
12373 Lancearmstrong, provisional designation , is a bright Vesta family, Vestian asteroid from the inner regions of the asteroid belt, approximately in diameter. It was discovered on 15 May 1994, by American astronomer and software engineer Charles de Saint-Aignan after examining films taken at Palomar Observatory, California, and named after American cyclist Lance Armstrong. Orbital and physical characteristics The asteroid orbits the Sun in the Kirkwood gap, inner main-belt at a distance of 2.2–2.7 Astronomical unit, AU once every 3 years and 10 months (1,401 days). Its orbit has an orbital eccentricity, eccentricity of 0.11 and an orbital inclination, inclination of 7Degree (angle), ° with respect to the ecliptic. The body's observation arc begins in 1994, as no precoveries were taken prior to its discovery. Based on an absolute Magnitude (astronomy), magnitude of 14.2 and an assumed astronomical albedo, albedo of 0.20, which is typical for bodies with a S-type a ...

Charles De Saint-Aignan
Charles P. de Saint-Aignan (born 16 February 1977, Paris) is an American software engineer who works for IBM on the IBM Watson project. He graduated from St. Paul's School (Concord, New Hampshire), in 1995, followed by Brown University (Providence, Rhode Island), in 1999. In 1994, de Saint-Aignan worked for Ted Bowell at Lowell Observatory, where he discovered a number of asteroids. He named his first discovery, 8710 Hawley, after Walter N. Hawley, who was his high school physics and astronomy teacher. The minor planet 5995 Saint-Aignan was named in de Saint-Aignan's honor on the occasion of his 20th birthday.
