26P/Grigg-Skjellerup is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has classified 26P/Grigg-Skjellerup 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.
26P/Grigg-Skjellerup orbits the sun every 1,930 days (5.28 years), coming as close as 1.11 AU and reaching as far as 4.96 AU from the sun. 26P/Grigg-Skjellerup is about 2.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
26P/Grigg-Skjellerup's orbit is 0.11 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.
26P/Grigg-Skjellerup has 2 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|April 15, 2146||11,212,836||14.908|
|March 11, 2161||19,604,908||17.466|
26P/Grigg-Skjellerup's orbit is determined by observations dating back to Dec. 19, 2007. It was last officially observed on Nov. 26, 2021. The IAU Minor Planet Center records 416 observations used to determine its orbit.
