Overview

378358 (2007 LD) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 LD as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 LD orbits the sun every 828 days (2.27 years), coming as close as 0.97 AU and reaching as far as 2.48 AU from the sun. Based on its brightness and the way it reflects light, 2007 LD is probably between 0.364 to 0.813 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.

Close Approaches

2007 LD's orbit is 0.03 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 LD has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
April 29, 2032 7,391,655 11.432
April 25, 2066 12,845,165 10.836
May 10, 2109 14,781,577 13.721
May 4, 2143 5,332,061 12.049
May 6, 2177 7,114,841 12.598
