Overview

154229 (2002 JN97) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 JN97 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 JN97 orbits the sun every 920 days (2.52 years), coming as close as 0.52 AU and reaching as far as 3.18 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2002 JN97 is probably between 1.255 to 2.806 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 2002 JN97 has been observed. It completes a rotation on its axis every 4.48 hours.

Close Approaches

2002 JN97's orbit is 0.16 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.

2002 JN97 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Feb. 11, 2050 25,983,944 21.044
July 28, 2077 27,365,991 24.884
Feb. 18, 2118 26,460,717 23.519
Aug. 4, 2145 24,222,462 22.141
Feb. 11, 2181 27,973,711 20.046
