2019 TK5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 TK5 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.
2019 TK5 orbits the sun every 376 days (1.03 years), coming as close as 0.82 AU and reaching as far as 1.22 AU from the sun. Based on its brightness and the way it reflects light, 2019 TK5 is probably between 0.006 to 0.025 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 TK5's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2019 TK5 has 41 close approaches predicted in the coming decades:

2019 TK5's orbit is determined by observations dating back to Oct. 8, 2019. It was last officially observed on May 24, 2023. The IAU Minor Planet Center records 43 observations used to determine its orbit.
2019 TK5 can be reached with a journey of 402 days. This trajectory would require a delta-v of 6.112 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 503,340 potential trajectories and launch windows to this asteroid.
