Overview

5604 (1992 FE) is a very 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 a small to average asteroid, 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 days.

1992 FE's spectral type (Tholen) / V (SMASSII) indicates that it is likely to contain magnesium silicate and iron silicate.

Close Approaches

1992 FE's orbit is 0.03 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.

1992 FE has 27 close approaches predicted in the coming decades:
