Overview
Kadlu is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Kadlu 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.
Kadlu orbits the sun every 1,470 days (4.02 years), coming as close as 1.29 AU and reaching as far as 3.77 AU from the sun. Based on its brightness and the way it reflects light, Kadlu is probably between 1.020 to 2.281 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
The rotation of Kadlu has been observed. It completes a rotation on its axis every 50.60 hours.
Close Approaches
Kadlu's orbit is 0.28 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.
Kadlu has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 27, 2070 | 29,685,418 | 4.387 |
| July 12, 2109 | 28,974,467 | 7.739 |
| July 15, 2163 | 28,163,778 | 8.213 |
Images and Observations
Kadlu's orbit is determined by observations dating back to Sept. 23, 1990. It was last officially observed on May 26, 2022. The IAU Minor Planet Center records 526 observations used to determine its orbit.
