Key Facts

Overview

2019 GN22 is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2019 GN22 as potentially hazardous because its orbit does not bring it close to Earth.

2019 GN22 orbits the sun every 32,700 days (89.53 years), coming as close as 11.40 AU and reaching as far as 28.60 AU from the sun. Based on its brightness and the way it reflects light, 2019 GN22 is probably between 15.295 to 34.201 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Denver.

No Close Approaches

2019 GN22's orbit is 10.40 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

2019 GN22's orbit is determined by observations dating back to March 23, 2015. It was last officially observed on June 6, 2019. The IAU Minor Planet Center records 60 observations used to determine its orbit.

Accessibility and Exploration

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