Overview

2004 KG1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 KG1 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.

2004 KG1 orbits the sun every 276 days (0.76 years), coming as close as 0.49 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2004 KG1 is probably between 0.042 to 0.093 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2004 KG1'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.

2004 KG1 has 40 close approaches predicted in the coming decades:
