Key Facts
- Categorized as a Centaur-class Asteroid
- Comparable in size to the Golden Gate Bridge
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2021 CE22 is a small asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2021 CE22 as potentially hazardous because its orbit does not bring it close to Earth.
2021 CE22 orbits the sun every 7,130 days (19.52 years), coming as close as 1.69 AU and reaching as far as 12.81 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2021 CE22 is probably between 0.427 to 0.955 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
No Close Approaches
2021 CE22's orbit is 0.72 AU from Earth's orbit at its closest point. This means that there is a very 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
2021 CE22's orbit is determined by observations dating back to Jan. 28, 2021. It was last officially observed on April 10, 2021. The IAU Minor Planet Center records 23 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
