14402 (1991 DB) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1991 DB 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.
1991 DB orbits the sun every 820 days (2.25 years), coming as close as 1.03 AU and reaching as far as 2.40 AU from the sun. 1991 DB is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 1991 DB has been observed. It completes a rotation on its axis every 2.26 hours.
1991 DB's orbit is 0.10 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.
1991 DB has 7 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|April 17, 2110||29,520,901||6.905|
|April 1, 2119||22,976,537||6.987|
