Key Facts

Overview

88269 (2001 KF77) is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2001 KF77 as potentially hazardous because its orbit does not bring it close to Earth.

2001 KF77 orbits the sun every 48,600 days (133.06 years), coming as close as 19.81 AU and reaching as far as 32.29 AU from the sun. Based on its brightness and the way it reflects light, 2001 KF77 is probably between 33.617 to 75.169 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.

No Close Approaches

2001 KF77's orbit is 18.80 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

2001 KF77's orbit is determined by observations dating back to May 22, 2001. It was last officially observed on May 2, 2006. The IAU Minor Planet Center records 19 observations used to determine its orbit.

Accessibility and Exploration

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