(1958) Chandra is an asteroid of the outer main belt , which the Argentine astronomer Carlos Ulrrico Cesco at El Leoncito Observatory, which on September 24, 1970, when Félix Aguilar Observatory ( IAU code 808) in Argentine El Leoncito National Park is discovered has been. The Yale University and Columbia University used the observatory as a branch to the southern sky to watch. Since 1990 it has been named Observatorio Carlos Cesco. Unsecured sightings of the asteroid had already taken place several times before: in April 1947 at the Algerian Observatoire astronomique de Bouzareah (1947 HD), on September 2, 1959 at the State Observatory Heidelberg-Königstuhl (1959 RG ₁ ) and on October 28, 1965 at the Goethe- Link Observatory in Indiana (1965 UN).

The mean diameter of the asteroid was calculated to be 34.278 km (± 0.220). It has a dark surface with an albedo of 0.082 (± 0.007).

(1958) Chandra was named on November 1, 1979 after the American - Indian astrophysicist Subrahmanyan Chandrasekhar , who received the 1983 Nobel Prize in Physics .
