Overview

2014 FN38 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2014 FN38 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.

2014 FN38 orbits the sun every 273 days (0.75 years), coming as close as 0.57 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2014 FN38 is probably between 0.008 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2014 FN38's orbit is 0.01 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.

2014 FN38 has 6 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
April 22, 2020 13,452,969 6.499
May 25, 2026 14,751,687 7.482
May 29, 2029 19,413,406 9.633
May 29, 2032 28,767,846 12.259
March 21, 2061 22,220,798 12.112
March 20, 2064 10,434,700 9.651

Images and Observations

2014 FN38's orbit is determined by observations dating back to March 28, 2014. It was last officially observed on April 4, 2014. The IAU Minor Planet Center records 38 observations used to determine its orbit.

Accessibility and Exploration

2014 FN38 can be reached with a journey of 274 days. This trajectory would require a delta-v of 11.894 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 8 potential trajectories and launch windows to this asteroid.
