Uranus. It doesn't roll like a barrel though.
Uranus is the only outer planet (and only planet in our solar system) that rotates on its side.
Uranus is the planet that is tilted 90 degrees on its side, causing it to rotate on its side as it orbits the Sun. This unique tilt is thought to be the result of a collision with a massive object early in its formation.
The planet Uranus is tilted "on its side" about 98 degrees to the orbital plane. But all planets in our solar system have some tilt to the side, including Earth which tiles about 23 degrees. (Mercury's tilt is very small.)
If you mean a locked orbit like some "hot Jupiter" exoplanets, then the answer is; one side of the planet will haveendless daylight and the other side a never ending night. In other words its "solar day" would last "for ever". Comment: that's not what the question says. It's about having no rotation at all. In that (unlikely) case the "sidereal day" would be, technically, infinite. The "solar day" would equal the length of the planet's year.
Uranus is known for rotating on its side, causing it to rotate almost straight up and down in relation to its orbit around the Sun. This unique orientation is thought to have been caused by a massive collision early in the planet's history.

Uranus rotates on its side, so it appears to rotate in a clockwise direction when viewed from above its north pole. This unique tilt is believed to have been caused by a collision with a planet-sized body early in its history.
Uranus is the only outer planet (and only planet in our solar system) that rotates on its side.
50%-50% ...... The planet does not rotate on its axis. Therefore, the side facing the sun receives complete sunlight .... while the opposite side of the planet is perpetually "dark".
Uranus spins on its side, causing it to rotate like a top rather than spinning like most planets which rotate vertically. This unusual orientation is likely the result of a past collision with a large object.
Only one planet rotates on it's side and Jupiter isn't it. Verticlally is my answer.

Uranus is sometimes compared to a barrel due to its unique tilt on its axis, causing it to rotate on its side like a rolling barrel. This tilt is believed to have been caused by a collision with another large celestial body early in the solar system's history.
The planet Uranus is nicknamed the sideways planet because it has a unique axial tilt of about 98 degrees, causing it to essentially rotate on its side compared to other planets that have a more upright axis of rotation.
Awesome
It has two barrels, side by side. Most call it a double barrel.
It orbits the sun but does not rotate like Earth. One side is always hot and one is aways cold.
