Overview
424482 (2008 DG5) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 DG5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2008 DG5 orbits the sun every 514 days (1.41 years), coming as close as 0.95 AU and reaching as far as 1.56 AU from the sun. Based on its brightness and the way it reflects light, 2008 DG5 is probably between 0.202 to 0.901 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2008 DG5's orbit is 0.02 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.
2008 DG5 has 15 close approaches predicted in the coming decades:

Images and Observations
2008 DG5's orbit is determined by observations dating back to March 28, 2001. It was last officially observed on March 2, 2022. The IAU Minor Planet Center records 286 observations used to determine its orbit.
Accessibility and Exploration
2008 DG5 can be reached with a journey of 346 days. This trajectory would require a delta-v of 8.785 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 11,849 potential trajectories and launch windows to this asteroid.
