What planet has the shortest day?
The planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.
Why is a day 23 hours and 56 minutes?
If our definition of a day was truly based on one complete rotation of the Earth on its axis — a 360 degree spin — then a day would be 23 hours, 56 minutes, and 4 seconds. … The mismatch of nearly 4 minutes is because the Earth must rotate more than 360 degrees between one dawn and the next.
Which planet spins the fastest?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
Is a day exactly 24 hours?

Is it true you don’t age in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
Can life survive on Mars?
NASA study: Life from Earth could survive on Mars, at least for a while. … Scientists say some microbes from Earth could survive on Mars, at least temporarily, raising new problems and possibilities for future exploration of the red planet.
How long is an hour on Mars?
