2019 JH7 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 JH7 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 JH7 orbits the sun every 360 days (0.99 years), coming as close as 0.70 AU and reaching as far as 1.28 AU from the sun. Based on its brightness and the way it reflects light, 2019 JH7 is probably between 0.002 to 0.009 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 JH7's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2019 JH7 has 11 close approaches predicted in the coming decades:

NASA Sentry has assessed impact risk for 2 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| May 17, 2114 | 0.00005 | 0.002093 |
| May 17, 2118 | 0.00004 | 0.00209 |
2019 JH7's orbit is determined by observations dating back to May 13, 2019. It was last officially observed on May 16, 2019. The IAU Minor Planet Center records 78 observations used to determine its orbit.
2019 JH7 can be reached with a journey of 450 days. This trajectory would require a delta-v of 8.116 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 8,582 potential trajectories and launch windows to this asteroid.
