Overview
2012 VB37 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 VB37 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.
2012 VB37 orbits the sun every 638 days (1.75 years), coming as close as 1.00 AU and reaching as far as 1.90 AU from the sun. Based on its brightness and the way it reflects light, 2012 VB37 is probably between 0.014 to 0.062 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2012 VB37's orbit is 0.01 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.
2012 VB37 has 10 close approaches predicted in the coming decades:

Images and Observations
2012 VB37's orbit is determined by observations dating back to Nov. 7, 2012. It was last officially observed on Nov. 9, 2019. The IAU Minor Planet Center records 40 observations used to determine its orbit.
Accessibility and Exploration
2012 VB37 can be reached with a journey of 434 days. This trajectory would require a delta-v of 10.299 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 1,642 potential trajectories and launch windows to this asteroid.
