2020 UQ4 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2020 UQ4 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2020 UQ4 orbits the sun every 1,250 days (3.42 years), coming as close as 1.04 AU and reaching as far as 3.50 AU from the sun. Based on its brightness and the way it reflects light, 2020 UQ4 is probably between 0.228 to 0.511 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2020 UQ4's orbit is 0.02 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.
2020 UQ4 has 4 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
July 13, 2054 | 1,472,639 | 9.494 |
July 26, 2098 | 6,655,764 | 9.986 |
July 24, 2142 | 4,754,661 | 9.814 |
Aug. 6, 2186 | 13,008,734 | 10.933 |
2020 UQ4's orbit is determined by observations dating back to Aug. 23, 2013. It was last officially observed on March 29, 2023. The IAU Minor Planet Center records 28 observations used to determine its orbit.
