Key Facts

Overview

Albert is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Albert 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.

Albert orbits the sun every 1,566 days (4.29 years), coming as close as 1.20 AU and reaching as far as 4.08 AU from the sun. Based on its brightness and the way it reflects light, Albert is probably between 2.211 to 4.944 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to Mount Everest.

The rotation of Albert has been observed. It completes a rotation on its axis every 5.80 days.

Albert's spectral type (Tholen) / S (SMASSII) indicates that it is likely to contain magnesium silicate and iron silicate.

No Close Approaches

Albert's orbit is 0.20 AU from Earth's orbit at its closest point. This means that there is an 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

Albert's orbit is determined by observations dating back to Oct. 4, 1911. It was last officially observed on Jan. 25, 2019. The IAU Minor Planet Center records 1,821 observations used to determine its orbit.

Accessibility and Exploration

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