Key Facts

Overview

147865 (2005 VN39) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2005 VN39 as potentially hazardous because its orbit does not bring it close to Earth.

2005 VN39 orbits the sun every 2,870 days (7.86 years), coming as close as 3.34 AU and reaching as far as 4.57 AU from the sun. 2005 VN39 is about 11.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

2005 VN39's orbit is 2.36 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

2005 VN39's orbit is determined by observations dating back to June 24, 1995. It was last officially observed on April 3, 2023. The IAU Minor Planet Center records 758 observations used to determine its orbit.

Accessibility and Exploration

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