Key Facts

Overview

162004 (1991 VE) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1991 VE 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.

1991 VE orbits the sun every 307 days (0.84 years), coming as close as 0.30 AU and reaching as far as 1.48 AU from the sun. Based on its brightness and the way it reflects light, 1991 VE is probably between 0.623 to 1.393 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

The rotation of 1991 VE has been observed. It completes a rotation on its axis every 13.49 hours.

No Close Approaches

1991 VE's orbit is 0.06 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

1991 VE's orbit is determined by observations dating back to Nov. 24, 1954. It was last officially observed on Nov. 26, 2020. The IAU Minor Planet Center records 1,110 observations used to determine its orbit.

Accessibility and Exploration

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