516396 (2000 WY28) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2000 WY28 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.
2000 WY28 orbits the sun every 766 days (2.10 years), coming as close as 1.16 AU and reaching as far as 2.11 AU from the sun. Based on its brightness and the way it reflects light, 2000 WY28 is probably between 0.254 to 0.568 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
2000 WY28's orbit is 0.18 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.
2000 WY28 has 3 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Nov. 24, 2021||26,810,574||10.453|
|Nov. 24, 2086||27,507,140||10.537|
|Nov. 25, 2172||26,804,841||10.463|
2000 WY28's orbit is determined by observations dating back to Nov. 20, 2000. It was last officially observed on Jan. 18, 2020. The IAU Minor Planet Center records 77 observations used to determine its orbit.
