535844 (2015 BY310) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 BY310 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 BY310 orbits the sun every 729 days (2.00 years), coming as close as 0.95 AU and reaching as far as 2.22 AU from the sun. Based on its brightness and the way it reflects light, 2015 BY310 is probably between 0.074 to 0.329 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2015 BY310 has been observed. It completes a rotation on its axis every 0.09 hours.
2015 BY310'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.
2015 BY310 has 20 close approaches predicted in the coming decades:

2015 BY310's orbit is determined by observations dating back to Jan. 18, 2015. It was last officially observed on July 5, 2021. The IAU Minor Planet Center records 380 observations used to determine its orbit.
2015 BY310 can be reached with a journey of 346 days. This trajectory would require a delta-v of 11.956 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 potential trajectories and launch windows to this asteroid.
