Overview

2019 FS2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 FS2 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.

2019 FS2 orbits the sun every 360 days (0.99 years), coming as close as 0.81 AU and reaching as far as 1.17 AU from the sun. Based on its brightness and the way it reflects light, 2019 FS2 is probably between 0.006 to 0.027 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 FS2's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2019 FS2 has 22 close approaches predicted in the coming decades:

Images and Observations

2019 FS2's orbit is determined by observations dating back to March 31, 2019. It was last officially observed on April 7, 2019. The IAU Minor Planet Center records 49 observations used to determine its orbit.

Accessibility and Exploration

2019 FS2 can be reached with a journey of 418 days. This trajectory would require a delta-v of 7.265 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 47,965 potential trajectories and launch windows to this asteroid.
