458452 (2011 BR15) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2011 BR15 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.
2011 BR15 orbits the sun every 298 days (0.82 years), coming as close as 0.63 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 2011 BR15 is probably between 0.193 to 0.865 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.
The rotation of 2011 BR15 has been observed. It completes a rotation on its axis every 6.41 hours.
2011 BR15's orbit is 0.06 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.
2011 BR15 has 24 close approaches predicted in the coming decades:

2011 BR15's orbit is determined by observations dating back to Feb. 6, 2002. It was last officially observed on Feb. 26, 2020. The IAU Minor Planet Center records 168 observations used to determine its orbit.
2011 BR15 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.935 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 4 potential trajectories and launch windows to this asteroid.
