Overview
2019 YV1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 YV1 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 YV1 orbits the sun every 375 days (1.03 years), coming as close as 0.90 AU and reaching as far as 1.13 AU from the sun. Based on its brightness and the way it reflects light, 2019 YV1 is probably between 0.016 to 0.071 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2019 YV1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2019 YV1 has 10 close approaches predicted in the coming decades:

Images and Observations
2019 YV1's orbit is determined by observations dating back to Dec. 21, 2019. It was last officially observed on Feb. 25, 2020. The IAU Minor Planet Center records 98 observations used to determine its orbit.
Accessibility and Exploration
2019 YV1 can be reached with a journey of 362 days. This trajectory would require a delta-v of 8.499 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 8,092 potential trajectories and launch windows to this asteroid.
