Overview

192559 (1998 VO) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 VO as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1998 VO orbits the sun every 407 days (1.11 years), coming as close as 0.83 AU and reaching as far as 1.32 AU from the sun. Based on its brightness and the way it reflects light, 1998 VO is probably between 0.143 to 0.638 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

1998 VO's orbit is 0.03 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.

1998 VO has 25 close approaches predicted in the coming decades:

Images and Observations

1998 VO's orbit is determined by observations dating back to Nov. 10, 1998. It was last officially observed on Nov. 13, 2018. The IAU Minor Planet Center records 589 observations used to determine its orbit.

Accessibility and Exploration

1998 VO can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.544 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 75 potential trajectories and launch windows to this asteroid.
