85770 (1998 UP1) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1998 UP1 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.
1998 UP1 orbits the sun every 364 days (1.00 years), coming as close as 0.65 AU and reaching as far as 1.34 AU from the sun. Based on its brightness and the way it reflects light, 1998 UP1 is probably between 0.211 to 0.472 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
1998 UP1's orbit is 0.08 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.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
1998 UP1's orbit is determined by observations dating back to Oct. 12, 1990. It was last officially observed on Oct. 13, 2016. The IAU Minor Planet Center records 493 observations used to determine its orbit.
