Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the San Francisco Bay (5.27 km diameter)
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
19144 (1989 UP1) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1989 UP1 as potentially hazardous because its orbit does not bring it close to Earth.
1989 UP1 orbits the sun every 1,300 days (3.56 years), coming as close as 1.86 AU and reaching as far as 2.79 AU from the sun. 1989 UP1 is about 5.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
No Close Approaches
1989 UP1's orbit is 0.87 AU from Earth's orbit at its closest point. This means that there is a very 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.
Images and Observations
1989 UP1's orbit is determined by observations dating back to Nov. 15, 1982. It was last officially observed on June 13, 2023. The IAU Minor Planet Center records 3,150 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
