138155 (2000 ES70)

Key Facts

• Categorized as a Amor-class Asteroid
• Comparable in size to the U.S. Pentagon
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

138155 (2000 ES70) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2000 ES70 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 ES70 orbits the sun every 888 days (2.43 years), coming as close as 1.23 AU and reaching as far as 2.39 AU from the sun. Based on its brightness and the way it reflects light, 2000 ES70 is probably between 0.952 to 2.128 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

The rotation of 2000 ES70 has been observed. It completes a rotation on its axis every 5.13 hours.

No Close Approaches

2000 ES70's orbit is 0.43 AU from Earth's orbit at its closest point. This means that there is a 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

2000 ES70's orbit is determined by observations dating back to Oct. 28, 1989. It was last officially observed on July 29, 2023. The IAU Minor Planet Center records 960 observations used to determine its orbit.

Accessibility and Exploration

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