Overview

19356 (1997 GH3) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1997 GH3 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.

1997 GH3 orbits the sun every 1,450 days (3.97 years), coming as close as 1.11 AU and reaching as far as 3.91 AU from the sun. 1997 GH3 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1997 GH3 has been observed. It completes a rotation on its axis every 6.71 hours.

1997 GH3's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

Close Approaches

1997 GH3's orbit is 0.12 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

1997 GH3 has 2 close approaches predicted in the coming decades:
