  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation

Overview

386847 (2010 LR33) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 LR33 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 LR33 orbits the sun every 804 days (2.20 years), coming as close as 0.91 AU and reaching as far as 2.47 AU from the sun. 2010 LR33 is about 0.7 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

No Close Approaches

2010 LR33'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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2010 LR33's orbit is determined by observations dating back to March 26, 2001. It was last officially observed on June 10, 2023. The IAU Minor Planet Center records 384 observations used to determine its orbit.

Accessibility and Exploration

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