10434

10434 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 19, 1989, by Japanese astronomer Tsutomu Seki at the Geisei Observatory in Japan. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun within the asteroid belt. Its orbit is relatively stable and does not pose any significant threat to Earth.

The asteroid has a diameter of approximately 10 kilometers and a rotation period of about 12.5 hours. It is believed to be composed of rocky material, typical of most asteroids in the main belt. The surface of 10434 is likely covered in regolith, a layer of loose, fragmented material resulting from impacts and other processes.

The asteroid's orbit has a semi-major axis of about 2.7 astronomical units (AU), with an eccentricity of 0.12 and an inclination of 11.5 degrees relative to the ecliptic plane. This means it completes one orbit around the Sun approximately every 4.5 Earth years.

10434 has not been visited by any spacecraft, and its composition and surface features remain largely unknown. However, it is part of ongoing studies to understand the composition and dynamics of the asteroid belt. The asteroid is named after the Japanese astronomer Tsutomu Seki, who discovered it.
