Key Facts

Overview

Esambaev is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Esambaev as potentially hazardous because its orbit does not bring it close to Earth.

Esambaev orbits the sun every 1,740 days (4.76 years), coming as close as 2.65 AU and reaching as far as 3.03 AU from the sun. Based on its brightness and the way it reflects light, Esambaev is probably between 7.491 to 16.751 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Esambaev has been observed. It completes a rotation on its axis every 4.63 hours.

No Close Approaches

Esambaev's orbit is 1.65 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

Esambaev's orbit is determined by observations dating back to Oct. 1, 1953. It was last officially observed on June 24, 2023. The IAU Minor Planet Center records 3,576 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
