Overview
2019 VJ2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 VJ2 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.
2019 VJ2 orbits the sun every 294 days (0.80 years), coming as close as 0.58 AU and reaching as far as 1.15 AU from the sun. Based on its brightness and the way it reflects light, 2019 VJ2 is probably between 0.010 to 0.047 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2019 VJ2's orbit is 0.02 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.
2019 VJ2 has 14 close approaches predicted in the coming decades:

Images and Observations
2019 VJ2's orbit is determined by observations dating back to Oct. 30, 2019. It was last officially observed on Nov. 5, 2019. The IAU Minor Planet Center records 18 observations used to determine its orbit.
Accessibility and Exploration
2019 VJ2 can be reached with a journey of 378 days. This trajectory would require a delta-v of 11.557 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 268 potential trajectories and launch windows to this asteroid.
