Following is a transcript of the video. Early in the history of our solar system, something mysteriously knocked Earth slightly off its axis. So today we tilt at 23.5 degrees. But what would ...

For the Earth, the rotation axis points toward a bright star ... Most scientists now think its spin has been reversed over time by tidal forces involving the Sun and Venus’ thick atmosphere.

It takes about 24 hours for Earth to complete one full spin around its axis. This rotation is why we experience day and night. Think of Earth as a massive spinning ball, with the equator moving at ...

That's how quickly Earth rotates on its axis, from West to East ... But, scientists have actually run simulations for a backwards-spinning Earth, because it happens to be a great way to test ...

On both of these days, the Earth completed its usual 24-hour ... shifting of the Earth’s axis as the planet is not perfectly spherical – could be linked to the spinning speeds.

As well as the Earth spinning on its axis, at the same time it is also orbiting the Sun. The Earth takes 365 and a quarter days to make one complete orbit of the Sun. This is why a year on Earth ...

and it's still spinning faster. While Earth is, on average, pretty reliable and takes 86,400 seconds to rotate around its axis, this is not perfect. ”When highly accurate atomic clocks were ...

That’s because the Earth is a sphere that constantly rotates on its axis:just like a basketball player spinning a ball on their finger – but at over 1,500 kilometres per hour! It takes 24 ...
