Which space probe? there have been many.
The frequency of the ultrasonic waves of the echo from a stationary object is the same as the frequency of the ultrasonic waves emitted by the probe. The echo frequency remains constant as it reflects off the stationary object back to the probe.
Frequencies typically refer to counts, or "how many". If you wanted to know the frequencies of students in a school by gender, you would simply be asking about "how many" boys and how many girls there are.
The probe frequency for ultrasonic testing of forged steel materials typically ranges from 2 to 10 MHz. The specific frequency chosen will depend on the thickness and grain size of the material being tested. Higher frequencies are suitable for detecting smaller defects in thinner materials, while lower frequencies are better for thicker materials with larger grain sizes.
They have never found an "anal probe" per say. They have found implanted pieces of metal in various people via CT scans. These pieces of metal have been removed in some people, and have been noted to emit radio frequencies that could be heard in outer space.

Many light frequencies give off heat. Infrared is one of those frequencies.
Many asteroids are not massive enough to cause a strong gravitational pull on a probe or a person.
