Key Facts

Overview

11700 (1998 FT115) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 FT115 as potentially hazardous because its orbit does not bring it close to Earth.

1998 FT115 orbits the sun every 1,770 days (4.85 years), coming as close as 2.33 AU and reaching as far as 3.39 AU from the sun. Based on its brightness and the way it reflects light, 1998 FT115 is probably between 5.896 to 13.184 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of 1998 FT115 has been observed. It completes a rotation on its axis every 5.40 hours.

No Close Approaches

1998 FT115's orbit is 1.32 AU from Earth's orbit at its closest point. This means that there is an extremely 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.
