202577

202577 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 17, 1960, by the Indiana Asteroid Program at Goethe Link Observatory in Indiana, United States. The asteroid is named after the Indiana town of Brownstown, which is located near the observatory. The discovery was made by Indiana University astronomer Frank K. Edmondson.

202577 has an estimated diameter of about 3.5 kilometers, based on its absolute magnitude of 15.0. Its orbit has a semi-major axis of approximately 2.7 astronomical units (AU), with an eccentricity of 0.13 and an inclination of 6.5 degrees relative to the ecliptic plane. The asteroid completes one orbit around the Sun every 4.4 Earth years.

The spectral classification of 202577 is S-type, indicating that it is composed primarily of silicate materials and nickel-iron. This classification is typical for most asteroids in the inner asteroid belt. The asteroid's rotation period is approximately 5.5 hours, as determined by photometric observations.

202577 is not a particularly notable asteroid, and it has not been the subject of any significant scientific studies or missions. However, its discovery and naming contribute to the ongoing effort to catalog and understand the population of asteroids in the solar system. The asteroid's orbit and physical characteristics provide valuable data for studies of the formation and evolution of the asteroid belt.
