2018 JH2 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2018 JH2 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.
2018 JH2 orbits the sun every 720 days (1.97 years), coming as close as 1.05 AU and reaching as far as 2.09 AU from the sun. Based on its brightness and the way it reflects light, 2018 JH2 is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 JH2's orbit is 0.06 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2018 JH2 has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|March 26, 2020||11,364,012||4.813|
2018 JH2's orbit is determined by observations dating back to May 10, 2018. It was last officially observed on June 2, 2018. The IAU Minor Planet Center records 35 observations used to determine its orbit.
