Overview

2017 LU is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2017 LU as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 LU orbits the sun every 1,560 days (4.27 years), coming as close as 1.05 AU and reaching as far as 4.21 AU from the sun. Based on its brightness and the way it reflects light, 2017 LU is probably between 0.518 to 1.159 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2017 LU'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.

2017 LU has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Aug. 25, 2034 24,982,457 12.252
July 6, 2188 23,619,669 11.952

Images and Observations

2017 LU's orbit is determined by observations dating back to June 8, 2017. It was last officially observed on May 12, 2021. The IAU Minor Planet Center records 179 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
