Overview

417871 (2007 MB24) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 MB24 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2007 MB24 orbits the sun every 938 days (2.57 years), coming as close as 0.56 AU and reaching as far as 3.19 AU from the sun. Based on its brightness and the way it reflects light, 2007 MB24 is probably between 0.576 to 1.288 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.

Close Approaches

2007 MB24'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 MB24 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 28, 2073 23,236,430 29.391
Dec. 26, 2091 15,592,729 30.339
Dec. 26, 2109 12,325,066 30.788
Dec. 27, 2127 15,580,366 30.351
Dec. 29, 2145 23,395,843 29.354
