136874 (1998 FH74)

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to the island of Manhattan (3.40 km diameter)
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

136874 (1998 FH74) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 FH74 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.

1998 FH74 orbits the sun every 1,190 days (3.26 years), coming as close as 0.25 AU and reaching as far as 4.15 AU from the sun. Its orbit is highly elliptical. 1998 FH74 is about 3.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1998 FH74 has been observed. It completes a rotation on its axis every 28.55 hours.

No Close Approaches

1998 FH74's orbit is 0.24 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.

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

Images and Observations

1998 FH74's orbit is determined by observations dating back to May 4, 1995. It was last officially observed on July 8, 2023. The IAU Minor Planet Center records 1,194 observations used to determine its orbit.
