Key Facts

Overview

136635 (1994 VA1) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1994 VA1 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.

1994 VA1 orbits the sun every 721 days (1.97 years), coming as close as 1.30 AU and reaching as far as 1.85 AU from the sun. Based on its brightness and the way it reflects light, 1994 VA1 is probably between 0.391 to 0.875 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 1994 VA1 has been observed. It completes a rotation on its axis every 42.00 hours.

No Close Approaches

1994 VA1's orbit is 0.31 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

1994 VA1's orbit is determined by observations dating back to Nov. 5, 1994. It was last officially observed on July 9, 2023. The IAU Minor Planet Center records 1,834 observations used to determine its orbit.

Accessibility and Exploration

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