2019 PO1

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a school bus or smaller
• Will pass within 13,671,250 km of Earth in 2019
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2019 PO1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 PO1 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 PO1 orbits the sun every 385 days (1.05 years), coming as close as 0.97 AU and reaching as far as 1.10 AU from the sun. Based on its brightness and the way it reflects light, 2019 PO1 is probably between 0.005 to 0.021 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 PO1'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 PO1 has 7 close approaches predicted in the coming decades:

NASA Sentry has assessed impact risk for 37 very close approach scenarios. Here are the top scenarios ordered by probability of impact:

Images and Observations

2019 PO1's orbit is determined by observations dating back to Aug. 9, 2019. It was last officially observed on Sept. 25, 2019. The IAU Minor Planet Center records 55 observations used to determine its orbit.

Accessibility and Exploration

2019 PO1 can be reached with a journey of 362 days. This trajectory would require a delta-v of 3.96 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 1,387,015 potential trajectories and launch windows to this asteroid.
