Ohio is in the top ten of U.S. states with the most sightings of unidentified flying objects, according to a study.

The report by outdoor activity and nature advocacy group Outforia says Ohio reported over 4,100 UFO sightings to the National UFO Reporting Center between the 1950s and February.

That number puts Ohio at number eight in the country for UFO reports, with California leading the U.S. with more than 15,000 sightings and North Dakota last in the nation with fewer than 265 reports.

Neighboring states to Ohio also making the top ten are New York at number five, Pennsylvania at number seven, and Michigan at number ten.
