The delta-V requirements for landing on an outer solar system body are… intense. New Horizons flew past Pluto at 14 km/s; in order to land, that relative speed would need to become zero. This concept likely requires new propulsion technology.

Agreed on being fascinating, though.

We've already landed on an outer solar system body, Saturn's moon Titan. https://en.wikipedia.org/wiki/Huygens_(spacecraft)

Titan does have the advantage of a thick atmosphere to allow descent by parachute, and a large parent body to capture the spacecraft into orbit.

Well if it is a planet 10x the size if earth it might have an atmosphere so we could aerobrake, no?
