What if Venus became Earth's moon? Explore how our planet would change if Earth’s twin, a planet almost the same size and ...

The sun rises from the east, and sets in the west - this is a well-established fact for the longest time, and this is due to ...

The remains of more than 160 deceased people reached orbit yesterday on a spacecraft that hitched a ride on a SpaceX rocket.

The planet's orbit is almost a perfect circle but is slightly tipped relative to Earth's path around our star. This means it's incredibly hard for the sun, Venus, and Earth to align in the right way.

A day is defined as the time it takes a planet to make one full rotation on its axis. A year is the time it takes a planet to orbit around the sun. Of course on Earth we know a day is 24 hours and ...

A day is defined as the time it takes a planet to make one full rotation on its axis which, on Earth, is 23 hours and 56 minutes. Meanwhile, a year is the time it takes a planet to orbit around ...

That’s 243 Earth days to rotate once — the longest rotation of any planet in the Solar System — and only 224.7 Earth days to complete an orbit of the Sun.

On Venus, that is very much the case. One Venusian day, which is one complete rotation on its axis, takes 243 Earth days, making it the longest day of any other planet in the solar system.

While the Venus year is shorter than ours (225 days), its rotation is very slow (243 days) and “retrograde” – the other way round to Earth.

But not Venus! Venus is an oddball. It spins in what is called a retrograde rotation, meaning it rotates in the opposite direction to its orbit.
