Key Facts

Overview

444745 (2007 JF43) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2007 JF43 as potentially hazardous because its orbit does not bring it close to Earth.

2007 JF43 orbits the sun every 89,900 days (246.13 years), coming as close as 32.01 AU and reaching as far as 46.51 AU from the sun. Based on its brightness and the way it reflects light, 2007 JF43 is probably between 220.067 to 492.085 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of West Virginia.

The rotation of 2007 JF43 has been observed. It completes a rotation on its axis every 9.52 hours.

No Close Approaches

2007 JF43's orbit is 31.00 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2007 JF43's orbit is determined by observations dating back to April 13, 2002. It was last officially observed on May 26, 2023. The IAU Minor Planet Center records 587 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
