Overview

2019 UG12 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 UG12 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.

2019 UG12 orbits the sun every 1,090 days (2.98 years), coming as close as 0.88 AU and reaching as far as 3.26 AU from the sun. Based on its brightness and the way it reflects light, 2019 UG12 is probably between 0.014 to 0.031 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 UG12's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2019 UG12 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Nov. 1, 2019 1,531,866 11.893
Oct. 25, 2022 9,212,980 13.802
Oct. 18, 2025 21,300,057 16.208

Images and Observations

2019 UG12's orbit is determined by observations dating back to Oct. 27, 2019. It was last officially observed on Nov. 1, 2019. The IAU Minor Planet Center records 32 observations used to determine its orbit.
