Because there's nothing stopping them spinning.
All the planets that we know about spin, yes. Some spin faster or slower, or on a different axis, but they all spin.
The inner planets travel faster around the Sun because they are closer, while the outer planets take more time. The outer planets spin faster on their axis than the inner planets.
Firstly they are all roughly spherical. Secondly they orbit the sun. Thirdly they spin on their axes.
Gravity keeps planets in orbit around the sun. If planets were not subject to the gravitational attraction of the sun, they would fly off into interstellar space. In addition, gravity is also what holds planets together. If there were no gravity, the planets, and the sun, would disintegrate under the force of their own spin. There would be nothing left of the solar system but an expanding cloud of gas and dust.
The planets are satellites of the sun. The moons are satellites of the planets. The moons revolve around the planets captured by their gravity, while the planets revolve around the sun captured by its gravity and the sun.
Because It Has To Spin Like Planets Do
The center of the galaxy.
no
All planets spin on their axes as well as orbiting the Sun.
no, all planets spin and all planets in our solar system revolve around the sun.
The spin of the Earth is residual from the formation of the solar system. The original "whirlpools" of matter started to spin as they orbited the sun due to the Coriolis force acting on them. This caused them to spin around the planets. his spin stayed after the planets firmed up into discrete balls
The gas giants, the four planets farthest from the Sun, do spin faster than the inner planets. However, rotational speed has almost nothing to do with the distance a planet is from the sun. Having said that, both the Sun and the Moon are responsible for the tides of the oceans which are still slowing the Earth down ever so slightly. The extremely slow rotation of Venus would have had other causes. The rotational speeds of planets are the product of 4½ billion years of events. The angular momentum of the protostellar disc would have been transferred to growing planets. In the case of the gas giants, the tidal effects at their great distance from the Sun are extremely small compared to their masses. So they are still spinning vigorously. Even Mercury, the closest planet to the Sun, is not rapidly losing its spin.
It is called the solar system, and includes the Sun, planets, dwarf planets, asteroids, and comets. It extends much farther than the farthest planets, but not as far as the other nearby stars.

The conservation of angular momentum affects the expected spin of planets by causing them to rotate at a relatively constant speed as they orbit the sun. This means that planets are likely to have a consistent spin rate over time due to the conservation of angular momentum.
it got hotter and begun to spin so fast.
