2019 KG3 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2019 KG3 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 collision.
2019 KG3 orbits the sun every 597 days (1.64 years), coming as close as 1.03 AU and reaching as far as 1.74 AU from the sun. Based on its brightness and the way it reflects light, 2019 KG3 is probably between 0.13 to 0.60 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the U.S. Capitol building.
2019 KG3's orbit is 0.04 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 KG3 has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|June 11, 2019||6,258,991||6.753|
2019 KG3's orbit is determined by observations dating back to May 29, 2019. It was last officially observed on June 2, 2019. The IAU Minor Planet Center records 25 observations used to determine its orbit.
2019 KG3 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.095 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 85 potential trajectories and launch windows to this asteroid.
