2018 TF3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 TF3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2018 TF3 orbits the sun every 1,140 days (3.12 years), coming as close as 0.60 AU and reaching as far as 3.66 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2018 TF3 is probably between 0.221 to 0.494 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2018 TF3 has been observed. It completes a rotation on its axis every 2.35 hours.
2018 TF3'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.
2018 TF3 has 11 close approaches predicted in the coming decades:
