2020 DT4 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 DT4 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.
2020 DT4 orbits the sun every 372 days (1.02 years), coming as close as 0.93 AU and reaching as far as 1.09 AU from the sun. Based on its brightness and the way it reflects light, 2020 DT4 is probably between 0.014 to 0.062 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 DT4's orbit is 0.05 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.
2020 DT4 has 12 close approaches predicted in the coming decades:

2020 DT4's orbit is determined by observations dating back to Feb. 27, 2020. It was last officially observed on March 15, 2020. The IAU Minor Planet Center records 37 observations used to determine its orbit.
2020 DT4 can be reached with a journey of 362 days. This trajectory would require a delta-v of 6.088 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 533,075 potential trajectories and launch windows to this asteroid.
