2019 RH1 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2019 RH1 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 RH1 orbits the sun every 723 days (1.98 years), coming as close as 1.06 AU and reaching as far as 2.10 AU from the sun. Based on its brightness and the way it reflects light, 2019 RH1 is probably between 0.027 to 0.060 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 RH1'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.
2019 RH1 has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Oct. 12, 2019||9,833,962||4.008|
2019 RH1's orbit is determined by observations dating back to Sept. 4, 2019. It was last officially observed on Sept. 6, 2019. The IAU Minor Planet Center records 21 observations used to determine its orbit.
