**1271 Isergina**
1271 Isergina is a carbonaceous asteroid located in the outer region of the main asteroid belt. It was discovered on October 22, 1931, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean Peninsula. The asteroid is named after the Russian astronomer Naum Isergin.
### Discovery and Naming
The asteroid was identified during a period of active asteroid discovery in the early 20th century. Its provisional designation was 1931 TN before receiving its permanent number and name. The naming honors Naum Isergin, who contributed to the field of astronomy in Russia.
### Orbital Characteristics
1271 Isergina orbits the Sun at a distance ranging approximately from 2.7 to 3.3 astronomical units (AU), completing one orbit roughly every 5.3 years. Its orbit exhibits a moderate eccentricity and an inclination of about 10 degrees relative to the ecliptic plane.
### Physical Properties
Classified as a C-type (carbonaceous) asteroid, 1271 Isergina is composed primarily of carbon-rich materials, which give it a dark surface with low albedo. Its estimated diameter is around 30 kilometers, although precise measurements vary depending on observational methods.
### Observation and Research
Observations of 1271 Isergina have contributed to understanding the composition and dynamics of outer main-belt asteroids. Its relatively stable orbit and typical characteristics make it a subject of interest in studies of asteroid belt population and evolution.
