Would be really interesting, since dunes would be way flatter than those we're used to on earth which can go up to 30% incline, but there would also be way less dunes in general with sand floating a lot less far with the strong gravity. (Unless the atmospere is super dense again)

The big question is if there is an athmosphere. Because athmospheric breaking would make landing way easier than having to spend tons and tons of dV to slow down, (and thta's after an interstellar travel) but a huge athmosphere, which is probable on a heavy planet like that (?) would make the planet a one-way trip.
