RemarksIt was difficult to accurately judge if the object was traveling N to S on a fairly steep descent or more NW to SE with a shallower angle, though I think it was the latter. I was driving eastbound on Hill Ave. past McCord Rd. in Toledo, OH, at 30-35 mph at the time of the sighting (April 10, 2019 12:49 AM EDT +/- 1 minute, verified by time on cell phone immediately after object disappeared from view), but slowed upon seeing the object to ~20-25 mph. I was passing near a wooded area approaching a highway embankment and overpass (I-475). The object entered my FOV through the trees to the NE, well above the embankment (i.e. I don't think it was a vehicle light passing on the highway), and disappeared behind the trees on the embankment to the SE (I had approached significantly closer to the overpass in the time it was visible, accelerating the object's disappearance). My windows were partly down and it was fairly quiet, but I didn't hear any sort of sound of an aircraft or other high speed object in the area (including highway traffic, of which there was little, if any). I pulled over in a parking lot ~half a mile down the road (beyond the overpass) and got out to listen for a delayed boom and look from east to zenith to west for any sort of lingering trail but perceived neither over the next ~2 minutes. Light pollution in the entire area is fairly bad. Cloud cover appeared to be minimal. There is a regional airport and US ANG base to the SW (Toledo Express Airport, TOL) with flight paths crossing through the airspace I observed the object apparently crossing, and a small airport to the ESE (Toledo Executive Airport, TDZ, which I don't think is equipped to operate after dark), as well as a small airstrip to the N in Lambertville, MI, which I think only serves daylight agricultural, observation, and recreational purposes. However, as a lifelong resident of the area, I am very accustomed to the day- and night-time sights and sounds of private, commercial, cargo, and military fixed-wing aircraft on approach and takeoff in various weather conditions, as well as helicopters that pass through the area, and I feel confident it was not an aircraft. Furthermore, while I expect military flights are not tracked on such sites, according to air traffic tracker flightradar24.com, the airspace in the region should have been empty at the time of the sighting. As to the object itself, it had an intensely bright white "core" with bluish-green coloring around the edges and in a short, faintly-lit tail. It appeared larger than any star or planet in the night sky, but significantly smaller than the moon, with an apparent diameter maybe 10-20% of the moon's. I was young when Hale-Bopp was visible (7 years old), but I felt that this object appeared to be similar in size to slightly larger than the Hale-Bopp nucleus in the sky, which having looked at some pictures of the comet, particularly some images through/near treetops and other terrestrial points of reference, I would

ColorWhite, with blue-green coloration around edges & short tail effect. (Re: brightness, I'm not sure how to respond. It was very intense; I feel it would've been visible passing in front of a full moon. However, at ~10-20% the apparent diameter of the moon,
