Is it impossible for some objects to reach terminal velocity?

更新:

If terminal velocity is when an object has no acceleration due to force of gravity and air resistance canceling out, some objects mathematically won't reach terminal velocity. For example: a parachute. Some people say that a parachute has a lower terminal velocity but really, it can never reach it right? The air resistance will never come to par with the force of earth's gravity (9.8 m/s)

    If an object is falling without getting any faster, than it's force due to gravity and wind resistance are equal. Every single object can reach this state, including the parachute.

    Hypothetically, a heavy streamlined object like a depleted uranium dart could take more distance to reach terminal velocity than the thickness of the atmosphere. But not, I think, on this planet.

    Each object will have it's own terminal velocity - so essentially no.
