2019 HM is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 HM 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 HM orbits the sun every 363 days (0.99 years), coming as close as 0.99 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2019 HM is probably between 0.120 to 0.530 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2019 HM'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 HM has 18 close approaches predicted in the coming decades:

2019 HM's orbit is determined by observations dating back to April 22, 2019. It was last officially observed on June 5, 2019. The IAU Minor Planet Center records 32 observations used to determine its orbit.
2019 HM can be reached with a journey of 362 days. This trajectory would require a delta-v of 3.933 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 2,438,171 potential trajectories and launch windows to this asteroid.
