Pahoehoe lava.
A rope shaped or billowy shaped flow is a form of basaltic lava known as Pahoehoe.
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
Saturn's surface has not been proven to be smooth. One of Saturn's moons have been confirmed to be smooth and mirror like though.
In general, we can say a surface is smooth if it's lack of any "grip" or textural features presents no friction.
Jupiter is a gas giant. It does not have a surface.
A rope shaped or billowy shaped flow is a form of basaltic lava known as Pahoehoe.
Pahoehoe lava flows are characterized as having a fairly smooth surface that resembles the twisted braids of rope. These particular flows a fed internally by a liquid beneath a solidified or partially solidified surface.
In terms of composition, basaltic lava is the most common type. When it flows it can be divided into two varieties: Pahoehoe which has a smooth, ropey texture, and a'a, which has a borken, jagged surface.
AA is a type of basaltic lava characterized by a rough, jagged surface due to rapid cooling and solidification. Pahoehoe is another type of basaltic lava with a smooth, ropy texture formed when the outer layer of lava cools and solidifies, while the molten interior continues to flow.
Pahoehoe lava forms by small pieces of lava from an irregular flow. It is typical in certain types of volcanoes such as shield volcanoes.

No it does not have to be smooth.
The leaves of Betula populifolia are smooth on the lower surface.
The rough surface is better than the smooth surface for the frictional force to act.
