Key Facts

Overview

147719 (2005 LL48) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2005 LL48 as potentially hazardous because its orbit does not bring it close to Earth.

2005 LL48 orbits the sun every 1,340 days (3.67 years), coming as close as 1.62 AU and reaching as far as 3.12 AU from the sun. Based on its brightness and the way it reflects light, 2005 LL48 is probably between 1.537 to 3.436 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2005 LL48's orbit is 0.61 AU from Earth's orbit at its closest point. This means that there is a very 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

2005 LL48's orbit is determined by observations dating back to Jan. 18, 1996. It was last officially observed on June 21, 2023. The IAU Minor Planet Center records 870 observations used to determine its orbit.

Accessibility and Exploration

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