Johnbrownlee is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Johnbrownlee as potentially hazardous because its orbit does not bring it close to Earth.
Johnbrownlee orbits the sun every 1,990 days (5.45 years), coming as close as 2.70 AU and reaching as far as 3.49 AU from the sun. Johnbrownlee is about 15.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.
Johnbrownlee's orbit is 1.69 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.
Johnbrownlee's orbit is determined by observations dating back to March 5, 1986. It was last officially observed on April 1, 2023. The IAU Minor Planet Center records 3,207 observations used to determine its orbit.
