Comet 23P/Brorsen-Metcalf is an object with a medium-length orbit that is highly inclined to the ecliptic plane of the solar system. NASA JPL has classified 23P/Brorsen-Metcalf as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
23P/Brorsen-Metcalf orbits the sun every 25,800 days (70.64 years), coming as close as 0.48 AU and reaching as far as 33.66 AU from the sun. Its orbit is highly elliptical.
23P/Brorsen-Metcalf's orbit is 0.19 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.
23P/Brorsen-Metcalf's orbit is determined by observations dating back to Aug. 1, 1847. It was last officially observed on Sept. 9, 1989. The IAU Minor Planet Center records 223 observations used to determine its orbit.
