Overview

2021 JM6 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2021 JM6 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.

2021 JM6 orbits the sun every 798 days (2.18 years), coming as close as 0.94 AU and reaching as far as 2.43 AU from the sun. Based on its brightness and the way it reflects light, 2021 JM6 is probably between 0.029 to 0.064 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2021 JM6's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2021 JM6 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
June 12, 2021 4,226,546 8.338
June 2, 2080 3,900,554 9.841
May 31, 2152 9,458,201 10.979

Images and Observations

2021 JM6's orbit is determined by observations dating back to May 8, 2021. It was last officially observed on June 7, 2021. The IAU Minor Planet Center records 43 observations used to determine its orbit.
