Overview
265482 (2005 EE) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 EE as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2005 EE orbits the sun every 438 days (1.20 years), coming as close as 0.76 AU and reaching as far as 1.50 AU from the sun. Based on its brightness and the way it reflects light, 2005 EE is probably between 0.100 to 0.446 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2005 EE has been observed. It completes a rotation on its axis every 2.65 hours.
Close Approaches
2005 EE'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.
2005 EE has 18 close approaches predicted in the coming decades:

Images and Observations
2005 EE's orbit is determined by observations dating back to May 14, 2004. It was last officially observed on April 12, 2023. The IAU Minor Planet Center records 462 observations used to determine its orbit.
Accessibility and Exploration
2005 EE can be reached with a journey of 370 days. This trajectory would require a delta-v of 11.998 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 1 potential trajectories and launch windows to this asteroid.
