Overview

481482 (2007 CA19) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 CA19 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 CA19 orbits the sun every 1,720 days (4.71 years), coming as close as 0.50 AU and reaching as far as 5.11 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2007 CA19 is probably between 0.810 to 1.812 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

2007 CA19's orbit is 0.02 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.

2007 CA19 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Oct. 2, 2102 19,298,308 27.576
March 17, 2136 21,961,534 28.298
Oct. 3, 2150 23,774,899 27.603
