Key Facts

Overview

16684 (1994 JQ1) is a average-sized asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1994 JQ1 as potentially hazardous because its orbit does not bring it close to Earth.

1994 JQ1 orbits the sun every 108,182 days (296.19 years), coming as close as 41.92 AU and reaching as far as 46.94 AU from the sun. Based on its brightness and the way it reflects light, 1994 JQ1 is probably between 110.804 to 247.765 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. state of Connecticut.

No Close Approaches

1994 JQ1's orbit is 40.91 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

1994 JQ1's orbit is determined by observations dating back to May 11, 1994. It was last officially observed on May 23, 2001. The IAU Minor Planet Center records 45 observations used to determine its orbit.

Accessibility and Exploration

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