Object flew past our aircraft at 10,000 feet within 200 yards of our right wing.

My wife and I were flying in our Cirrus SR22T from KAGC to KDPA. We were at 10,000 feet altitude and traveling at ~200 MPH on an Instrument flight plan. The weather was VMC, outside air temperature was 5 C. We were in contact with South Bend ATC.
The object was approaching us rapidly about 200 yards north of our position. We were just south of Bass Lake, Indiana and north of Wheeler Airport (IG05) at 6:49PM EDT.
We both were shocked to see an object at our exact altitude and so close to the airplane. We contacted ATC to ask if they had seen anything on their radar. They indicated they did not have anything showing up in our location but had indicated there was a commercial aircraft 30,000 feet above us.
They asked us to describe the object. It was of metal material and color. It had a sphere on the top with what appeared to be a black visor across the facing position. Under the attached sphere were three attached rectangular cubes stacked vertically. The entire object appeared to be about 2-3 meters in vertical length.
No obvious form of propulsion on the object. It was moving horizontally at a high rate of speed or at least it appeared to be, however we were also moving fast so we aren’t sure if the object was move or if it was just us moving.
This was not a drone, bird, or aircraft. It almost appeared as a automated jet-pack like structure with a monitoring head but without extremities of arms or legs.
I have been a pilot for 25 years and have flown over 800 hours of flight time. My wife has flown many missions with me and is a keen observer of other aircraft while flying.
