2013 TT5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 TT5 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.
2013 TT5 orbits the sun every 398 days (1.09 years), coming as close as 0.96 AU and reaching as far as 1.16 AU from the sun. Based on its brightness and the way it reflects light, 2013 TT5 is probably between 0.010 to 0.043 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2013 TT5'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.
2013 TT5 has 27 close approaches predicted in the coming decades:

2013 TT5's orbit is determined by observations dating back to Oct. 3, 2013. It was last officially observed on Oct. 16, 2013. The IAU Minor Planet Center records 28 observations used to determine its orbit.
2013 TT5 can be reached with a journey of 370 days. This trajectory would require a delta-v of 5.557 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 212,025 potential trajectories and launch windows to this asteroid.
