Overview

2013 KZ1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2013 KZ1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 KZ1 orbits the sun every 713 days (1.95 years), coming as close as 0.77 AU and reaching as far as 2.35 AU from the sun. Based on its brightness and the way it reflects light, 2013 KZ1 is probably between 0.133 to 0.298 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 KZ1's orbit is 0.03 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.

2013 KZ1 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Nov. 12, 2050 14,542,300 19.100
Nov. 15, 2091 5,326,669 20.432
Nov. 26, 2130 29,185,448 25.072
Nov. 12, 2132 17,229,088 18.786
Nov. 20, 2171 8,193,918 21.841
