Overview

2019 JG is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 JG 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 JG orbits the sun every 424 days (1.16 years), coming as close as 0.80 AU and reaching as far as 1.41 AU from the sun. Based on its brightness and the way it reflects light, 2019 JG is probably between 0.038 to 0.086 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 JG'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 JG has 20 close approaches predicted in the coming decades:
