Key Facts

Overview

13148 (1995 EF) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1995 EF as potentially hazardous because its orbit does not bring it close to Earth.

1995 EF orbits the sun every 1,710 days (4.68 years), coming as close as 2.35 AU and reaching as far as 3.25 AU from the sun. 1995 EF is about 10.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.

No Close Approaches

1995 EF's orbit is 1.36 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.

Images and Observations

1995 EF's orbit is determined by observations dating back to Dec. 2, 1994. It was last officially observed on May 30, 2023. The IAU Minor Planet Center records 2,321 observations used to determine its orbit.

Accessibility and Exploration

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