Overview

434326 (2004 JG6) is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2004 JG6 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2004 JG6 orbits the sun every 185 days (0.51 years), coming as close as 0.30 AU and reaching as far as 0.97 AU from the sun. Based on its brightness and the way it reflects light, 2004 JG6 is probably between 0.555 to 1.242 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2004 JG6's orbit is 0.04 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2004 JG6 has 32 close approaches predicted in the coming decades:
