Key Facts

Overview

141424 (2002 CD) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 CD 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.

2002 CD orbits the sun every 354 days (0.97 years), coming as close as 0.81 AU and reaching as far as 1.15 AU from the sun. Based on its brightness and the way it reflects light, 2002 CD is probably between 0.138 to 0.618 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

No Close Approaches

2002 CD's orbit is 0.07 AU from Earth's orbit at its closest point. This means that there is an 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

2002 CD's orbit is determined by observations dating back to Feb. 1, 2002. It was last officially observed on July 26, 2007. The IAU Minor Planet Center records 297 observations used to determine its orbit.

Accessibility and Exploration

2002 CD can be reached with a journey of 410 days. This trajectory would require a delta-v of 8.585 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 118,067 potential trajectories and launch windows to this asteroid.
