Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to the Golden Gate Bridge (0.55 km diameter)
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation

Overview

5604 (1992 FE) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1992 FE as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1992 FE orbits the sun every 327 days (0.90 years), coming as close as 0.55 AU and reaching as far as 1.31 AU from the sun. 1992 FE is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1992 FE has been observed. It completes a rotation on its axis every 5.34 hours.

1992 FE's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

No Close Approaches

1992 FE's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an 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

1992 FE's orbit is determined by observations dating back to April 23, 1976. It was last officially observed on March 24, 2020. The IAU Minor Planet Center records 940 observations used to determine its orbit.

Accessibility and Exploration

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