Frequently Asked Questions
Does potentially hazardous mean it will hit Earth?
No. It is an orbital classification based on factors such as size and potential approach distance, not a prediction of impact.
Where does the data come from?
The tool uses NASA NeoWs data maintained from NASA/JPL near-Earth object information.
