This is how planets of the solar system rotate

Rogue Satellite out now on Youtube

We are currently hurtling through the cosmos at astonishing speeds. This animation illustrates the varying velocities at play, from the Earth's rotation to the movement of our entire galaxy.

Note: A stabilized camera reveals Earth's rotation by keeping the camera steady while the Earth moves beneath it. This setup shows the Earth rotating, with the stars appearing stationary in the background. It's a clear demonstration of our planet's daily spin, visible when capturing long-exposure or time-lapse footage.

Earth rotates around an imaginary line called its axis, which runs from the North Pole to the South Pole. This spinning motion happens from west to east, making the Sun appear to rise in the east and set in the west. One full rotation takes about 24 hours, which gives us day and night. This rotation also affects wind patterns and the movement of ocean currents, creating phenomena like the Coriolis effect, which influences weather systems and cyclones. The tilt of the axis, combined with Earth’s orbit around the Sun, is also responsible for the changing seasons. Over time, Earth's rotation is slowly slowing down because of the Moon's gravitational pull, a process known as tidal braking. This causes the oceans’ tides to create friction against Earth’s surface, gradually reducing its speed. As a result, days are getting slightly longer by about 1.7 milliseconds per century. For example, millions of years ago during the time of dinosaurs, a day on Earth lasted about 23 hours. In the distant future, this process will continue, potentially making days even longer. Sometimes, Earth's rotation speed changes slightly. For example, on June 29, 2022, Earth completed its rotation 1.59 milliseconds faster than usual, marking the shortest day ever recorded. These small changes can happen because of shifts in Earth's molten core, movements of tectonic plates, large-scale weather events like El Niño, or even the redistribution of water due to melting polar ice caps. Natural disasters like major earthquakes can also alter Earth's rotation slightly by shifting its mass, much like a figure skater pulling in their arms to spin faster.

It's weird, it makes it look like Earth is rotating around the camera, while in reality it is rotating on its axis.

The camera is mounted on an equatorial mount.

It's beautiful, but still the question of is it flat or not?

No nice to see the opposite of the spinning stars time lapse. The stars are not moving (to our eye), we are.

Flat-earthers aren't going to like this.

Still the flat earthers won't approve of it. 🤦♂️
