53429 (1999 TF5) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 TF5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1999 TF5 orbits the sun every 1,050 days (2.87 years), coming as close as 0.73 AU and reaching as far as 3.32 AU from the sun. Based on its brightness and the way it reflects light, 1999 TF5 is probably between 0.433 to 0.968 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
1999 TF5's orbit is 0.05 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.
1999 TF5 has 2 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
April 7, 2097 | 10,190,511 | 21.312 |
March 25, 2169 | 26,752,212 | 26.657 |
1999 TF5's orbit is determined by observations dating back to Oct. 3, 1999. It was last officially observed on Oct. 29, 2022. The IAU Minor Planet Center records 148 observations used to determine its orbit.
