162421 (2000 ET70) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 ET70 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 ET70 orbits the sun every 336 days (0.92 years), coming as close as 0.83 AU and reaching as far as 1.06 AU from the sun. Based on its brightness and the way it reflects light, 2000 ET70 is probably between 0.668 to 1.493 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.
The rotation of 2000 ET70 has been observed. It completes a rotation on its axis every 8.95 hours.
2000 ET70's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an 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.
2000 ET70's orbit is determined by observations dating back to Feb. 18, 1977. It was last officially observed on Feb. 11, 2021. The IAU Minor Planet Center records 379 observations used to determine its orbit.
