2007 WJ3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 WJ3 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.
2007 WJ3 orbits the sun every 476 days (1.30 years), coming as close as 0.75 AU and reaching as far as 1.64 AU from the sun. Based on its brightness and the way it reflects light, 2007 WJ3 is probably between 0.015 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2007 WJ3's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2007 WJ3 has 2 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Nov. 20, 2020||21,339,872||15.921|
|May 18, 2028||4,517,636||12.567|
2007 WJ3's orbit is determined by observations dating back to Nov. 16, 2007. It was last officially observed on Nov. 20, 2007. The IAU Minor Planet Center records 43 observations used to determine its orbit.
