- Classified as a Near Earth Asteroid (NEA)
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2015 CB is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2015 CB 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.
2015 CB orbits the sun every 335 days (0.92 years), coming as close as 0.75 AU and reaching as far as 1.14 AU from the sun. Based on its brightness and the way it reflects light, 2015 CB is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2015 CB's orbit is 0.05 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.
2015 CB has 20 close approaches predicted in the coming decades:
