42237 (2001 EG21) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2001 EG21 as potentially hazardous because its orbit does not bring it close to Earth.
2001 EG21 orbits the sun every 2,890 days (7.91 years), coming as close as 3.46 AU and reaching as far as 4.48 AU from the sun. 2001 EG21 is about 18.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 2001 EG21 has been observed. It completes a rotation on its axis every 6.38 hours.
2001 EG21's orbit is 2.46 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.
2001 EG21's orbit is determined by observations dating back to April 6, 1994. It was last officially observed on March 26, 2023. The IAU Minor Planet Center records 2,281 observations used to determine its orbit.
