2017 UT5

Key Facts

• Categorized as a Amor-class Asteroid
• Comparable in size to a school bus or smaller
• Will pass within 29,324,579 km of Earth in 2019
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2017 UT5 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2017 UT5 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.

2017 UT5 orbits the sun every 743 days (2.03 years), coming as close as 1.04 AU and reaching as far as 2.17 AU from the sun. Based on its brightness and the way it reflects light, 2017 UT5 is probably between 0.010 to 0.023 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2017 UT5's orbit is 0.05 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.

2017 UT5 has 1 close approaches predicted in the coming decades:
