2004 DA53 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 DA53 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 DA53 orbits the sun every 303 days (0.83 years), coming as close as 0.59 AU and reaching as far as 1.18 AU from the sun. Based on its brightness and the way it reflects light, 2004 DA53 is probably between 0.004 to 0.020 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2004 DA53'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 DA53 has 23 close approaches predicted in the coming decades:

2004 DA53's orbit is determined by observations dating back to Feb. 26, 2004. It was last officially observed on Feb. 27, 2004. The IAU Minor Planet Center records 17 observations used to determine its orbit.
2004 DA53 can be reached with a journey of 378 days. This trajectory would require a delta-v of 10.602 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 6,637 potential trajectories and launch windows to this asteroid.
