Key Facts

Overview

2010 NG146 is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2010 NG146 as potentially hazardous because its orbit does not bring it close to Earth.

2010 NG146 orbits the sun every 32,800 days (89.80 years), coming as close as 17.65 AU and reaching as far as 22.45 AU from the sun. Based on its brightness and the way it reflects light, 2010 NG146 is probably between 42.516 to 95.069 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.

No Close Approaches

2010 NG146's orbit is 16.70 AU from Earth's orbit at its closest point. This means that there is an extremely 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 NG146's orbit is determined by observations dating back to July 16, 2009. It was last officially observed on July 26, 2023. The IAU Minor Planet Center records 156 observations used to determine its orbit.

Accessibility and Exploration

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