2018 DB is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 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.
2018 DB orbits the sun every 728 days (1.99 years), coming as close as 0.70 AU and reaching as far as 2.47 AU from the sun. Based on its brightness and the way it reflects light, 2018 DB is probably between 0.008 to 0.018 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 DB's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2018 DB has 1 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Feb. 14, 2020||17,583,292||19.550|
NASA Sentry has assessed impact risk for 3 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
|Date||Distance from Earth (km)||Distance Error (km)||Probability of Impact (%)||Impact Energy (Mt)|
|Feb. 24, 2119||1,701.30||±831.33||0.00011||0.06828|
|Feb. 23, 2068||12,024.66||±3,660.56||0.00001||0.06817|
|Aug. 6, 2082||7,665.48||±994.46||0.00000||0.06686|
2018 DB's orbit is determined by observations dating back to Feb. 12, 2018. It was last officially observed on Feb. 19, 2018. The IAU Minor Planet Center records 19 observations used to determine its orbit.
