388945 (2008 TZ3) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 TZ3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2008 TZ3 orbits the sun every 733 days (2.01 years), coming as close as 0.97 AU and reaching as far as 2.22 AU from the sun. Based on its brightness and the way it reflects light, 2008 TZ3 is probably between 0.220 to 0.492 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2008 TZ3 has been observed. It completes a rotation on its axis every 39.15 hours.
2008 TZ3'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.
2008 TZ3 has 18 close approaches predicted in the coming decades:
