Key Facts

Overview

A/2017 U7 is a relatively small asteroid with an orbit not bound to the sun. NASA JPL has not classified A/2017 U7 as potentially hazardous because its orbit does not bring it close to Earth.

A/2017 U7 orbits the sun every 0 days (0.00 years), coming as close as 6.29 AU and reaching as far as -15740.29 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, A/2017 U7 is probably between 20.163 to 45.086 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the city of Indianapolis.

No Close Approaches

A/2017 U7's orbit is 5.47 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

A/2017 U7's orbit is determined by observations dating back to Aug. 18, 2017. It was last officially observed on Nov. 27, 2019. The IAU Minor Planet Center records 423 observations used to determine its orbit.

Accessibility and Exploration

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