53430 (1999 TY16) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1999 TY16 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.
1999 TY16 orbits the sun every 1,110 days (3.04 years), coming as close as 1.25 AU and reaching as far as 2.95 AU from the sun. 1999 TY16 is about 1.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.
The rotation of 1999 TY16 has been observed. It completes a rotation on its axis every 9.58 hours.
1999 TY16's orbit is 0.29 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
1999 TY16's orbit is determined by observations dating back to Oct. 13, 1999. It was last officially observed on Feb. 6, 2021. The IAU Minor Planet Center records 890 observations used to determine its orbit.
