Overview

533011 (2014 AY28) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2014 AY28 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2014 AY28 orbits the sun every 622 days (1.70 years), coming as close as 1.02 AU and reaching as far as 1.83 AU from the sun. Based on its brightness and the way it reflects light, 2014 AY28 is probably between 0.074 to 0.332 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

The rotation of 2014 AY28 has been observed. It completes a rotation on its axis every 0.91 hours.

Close Approaches

2014 AY28's orbit is 0.04 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.

2014 AY28 has 8 close approaches predicted in the coming decades:

Images and Observations

2014 AY28's orbit is determined by observations dating back to Jan. 4, 2014. It was last officially observed on Dec. 18, 2018. The IAU Minor Planet Center records 378 observations used to determine its orbit.

Accessibility and Exploration

2014 AY28 can be reached with a journey of 370 days. This trajectory would require a delta-v of 11.761 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 20 potential trajectories and launch windows to this asteroid.
