What determines how fast a planet spins?
The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon)..
How long is 1 year in space?
Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. It’s not exactly this simple though. An Earth year is actually about 365 days, plus approximately 6 hours.
Is there life on Venus?
To date, no definitive proof has been found of past or present life on Venus. … With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.
Why does the earth keep spinning?
“The Earth keeps spinning because it was born spinning,” Luhman said. Different planets have different rates of rotation. Mercury, closest to the sun, is slowed by the sun’s gravity, Luhman noted, making but a single rotation in the time it takes the Earth to rotate 58 times.

Which is the most dangerous planet?
Venus0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
Which planet is smallest?
MercuryMercury is the smallest planet in our solar system—only slightly larger than Earth’s Moon.

Is an hour in space 7 years on earth?
No. The time-dilation effect of Einstein’s relativity has nothing to do with space. … The faster you’re moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then yes, you could miss 7 years on Earth every hour.
Will the earth ever stop spinning?
The Earth will never stop rotating. Earth rotates in the purest, most perfect vacuum in the whole universe—empty space. Space is so empty, so devoid of anything to slow the Earth down, that it just spins and spins, practically without friction.
Why dont we feel the earth spinning?
Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.
Which planet spins the fastest?
JupiterGood luck getting any sleep on Jupiter! This humongous gas giant rotates faster than any other planet in the Solar System, completing a day in less than 10 hours!
