Class V planetary probe
From Memory Alpha, the free Star Trek reference
The class V planetary probe is a probe carried aboard Federation starships for planetary analysis. It is equiped with visual sensors, as well as sensors that can detect the chemical contents of an atmosphere, and geological sensors. Its orbit is maintained with impulse thrusters.
A class 5 probe was used by the USS Voyager in 2376 to gather information about Kelemane's planet when the ship was trapped in orbit above the planet. Data returned by the probe indicated that the civilization on the surface had advanced to an industrial level. It also reported the frequency of the seismic distubances caused by Voyager's presence.

The class V planetary probe is a re-use of the multispatial probe from "Extreme Risk" and was later modified to represent a Quarra buoy in "Workforce".
