2010 TW54 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 TW54 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.
2010 TW54 orbits the sun every 389 days (1.07 years), coming as close as 0.80 AU and reaching as far as 1.29 AU from the sun. Based on its brightness and the way it reflects light, 2010 TW54 is probably between 0.005 to 0.023 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2010 TW54's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2010 TW54's orbit is determined by observations dating back to Oct. 11, 2010. It was last officially observed on Oct. 16, 2010. The IAU Minor Planet Center records 70 observations used to determine its orbit.
2010 TW54 can be reached with a journey of 394 days. This trajectory would require a delta-v of 8.046 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 79,631 potential trajectories and launch windows to this asteroid.
