2011 LJ1

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to the U.S. Capitol building
• Will pass within 26,927,959 km of Earth in 2026
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2011 LJ1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 LJ1 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.

2011 LJ1 orbits the sun every 1,370 days (3.75 years), coming as close as 0.74 AU and reaching as far as 4.09 AU from the sun. Based on its brightness and the way it reflects light, 2011 LJ1 is probably between 0.367 to 0.820 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2011 LJ1's orbit is 0.07 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.

2011 LJ1 has 6 close approaches predicted in the coming decades:

Images and Observations

2011 LJ1's orbit is determined by observations dating back to June 4, 2011. It was last officially observed on Dec. 26, 2022. The IAU Minor Planet Center records 135 observations used to determine its orbit.
