Overview

2017 QW1 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2017 QW1 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.

2017 QW1 orbits the sun every 357 days (0.98 years), coming as close as 0.86 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2017 QW1 is probably between 0.100 to 0.450 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 QW1's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2017 QW1 has 13 close approaches predicted in the coming decades:

Images and Observations

2017 QW1's orbit is determined by observations dating back to Aug. 18, 2017. It was last officially observed on Aug. 30, 2017. The IAU Minor Planet Center records 36 observations used to determine its orbit.

Accessibility and Exploration

2017 QW1 can be reached with a journey of 370 days. This trajectory would require a delta-v of 5.799 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 237,546 potential trajectories and launch windows to this asteroid.
