Rotation Speed facts

While investigating facts about Rotation Speed Of Earth and Rotation Speed Of Planets, I found out little known, but curios details like:

The NFL uses tracking chips embedded in players shoulder pads to record a players every move on the field. They are also located inside footballs to track: velocity, rotation ,ball speed and location.

how does speed dating rotation work?

The Japanese earthquake in 2011 increased the Earth's rotation speed, shortening the day by 1.8 microseconds.

What is the speed of earth rotation?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering at what latitudes) on earth is the speed of rotation the greatest. Here are 40 of the best facts about Rotation Speed Of Moon and Rotation Speed Of Sun I managed to collect.

why is the speed of rotation greatest at the equator?

  1. An armored vehicle prototype invented by Preston Tucker in 1930s. Tucker Tiger, as it was called, was entirely bulletproof, had air conditioning, and a turret that could rotate 360 degrees. Its maximum speed was 114 mph, but it was rejected by the Army because they felt it was too fast.

  2. Arthur Ganson's "Machine with Concrete", a kinetic sculpture of 12 connected gear pairs with the last gear stuck in concrete. It can still turn though, due to gear reduction that cuts the rotational speed by 1/50th for each gear set. The last gear will take over 2 trillion years to turn once.

  3. If Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.

  4. The theory that in 'Superman' (1978), Superman doesn't actually turn back time by litterally reversing the earth's rotation. Instead, he himself travels to the past by flying faster than the speed of light, and the reversing earth is simply a visual metaphor for this.

  5. The 2011 earthquake in Japan was so powerful it moved Honshu (the main island of Japan) 2.4m (8 ft) to the east, shifted the Earth on its axis by estimates of between 10 cm and 25 cm, and increased earth's rotational speed by 1.8 µs per day.

  6. The neutron star 'PSR J1748-2446ad' rotates on its axis 716 times per second, and is the fastest spinning known neutron star. At its equator, it spins at 24 percent of the speed of light.

  7. Neutron star PSR J1748-2446 is the fastest spinning celestial object in the universe. The star rotates 716 times every second, so its equator moves at about 25% the speed of light. It is also 50 trillion times the density of lead and has a magnetic field a trillion times stronger than the Sun’s.

  8. The Voyager 2 carried a tape recorder whose reels rotated at high speeds which caused issues with its operations. Due to the conservation of angular momentum, the space probe started an undesirable rotation in the opposite direction whenever the tape recorder was turned on.

  9. Due to irregularities in Earth's rotation speed, clocks sometimes strike 23:59:60 to stay in sync with a day's real duration, essentially creating minutes with 61 seconds.

  10. The 2011 earthquake near Japan increased the Earth's rotation speed, shortening the day by 1.8 microseconds.

rotation speed facts
What is the speed of earth rotation on its axis?

Why is the speed of rotation decreases near the pole?

You can easily fact check why is the speed of earth rotation different at the equator by examining the linked well-known sources.

In 2011 earthquake near Japan increased the Earth's rotation speed, shortening the day by 1.8 microseconds.

He made these determinations by improving on the design of the rotating mirror that had originally been used to measure speed of light.

Uranus is the seventh planet from the Sun, it has the third largest planetary radius and the fourth largest planetary mass in the Solar System. Uranus is unique because its axis of rotation is always tilted sideways, which means that its north and south poles are where other planets have their equators. Wind speeds can reach up to 560 miles per hour (900 kilometers per hour).

In 1862 Foucault used a rotating mirror in an enclosed space to accurately determine the speed of light and he became interested in precision engineering.

The speed of light was calculated in 1849 using mirrors and a rotating cog. The value was more precise than the previously accepted value from 1676. - source

When considering crankshaft and camshaft rotation speeds which is true?

Modern cars measure the tire-pressure by sensing individual tire rotation and comparing it to speed and other sensory inputs.

How to calculate earth rotation speed?

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator, and all of the land masses would be scoured clean of anything not attached to bedrock.

Because of the planet Mercury's orbit and rotational speed, some areas of the planet can experience two sunrises and sunsets per day.

The fastest spinning star discovered is a pulsar named PSR J1748−2446ad and is part of a globular cluster called Terzan 5 in the constellation Sagittarius 18,000 light-years from Earth. It rotates at 24% of the speed of light or 716 times per second at its equator.

The same side of the Moon is always facing the Earth due to 'tidal locking'. The Moon rotates at the exact same speed as it takes to orbit the Earth (28 days).

The tides are slowly slowing down the earth's rotation and speeding up the moon's orbit, therefore moving it away from us.

Interesting facts about rotation speed

The length of a year was 420 days millions of years ago based on the growth rings of fossilized coral specimens. They show that the number of days in a year are slowly decreasing as the Earth's rotation speed slows and the moon moves further away.

While flying west on a Concorde jet at top speed, passengers could observe the Sun rising since the plane could fly faster than the rotation of the Earth.

Isaac Newton theorized a zenith telescope a long time before the first one was built. He couldn"t build a zenith telescope because he couldn"t control the rotation speed of the liquid.

The Ferranti Mark 1 -- "the first commercially available general-purpose computer" -- "could store just over a kilobyte of data in cathode-ray tubes for high-speed access; a rotating magnetic drum offered 82 kilobytes of permanent storage."

Different parts of the sun rotate at different speeds

How do the speeds at which we are moving with earth's rotation?

Our sun rotates the Milky Way Galaxy at a speed of 828,000 km/second, but even at that speed it take the solar system approximately 230 million years to make one orbit around the galaxy.

We are slowly gaining weight due to the fact that our Earth is slowing. If/ when our Earth’s rotation stops you will gain .3% body weight relevant from the rotation speed of Earth today. But if our Earth’s rotation increased 8.5 times faster, a 200 pound male would weigh 100 pounds.


The much larger tandem propeller Chinook, can reach greater speeds than both the Apache and Blackhawk, due to its opposing rotating blades.

We are constantly moving at extreme speeds, even when we think we're still. We are on an Earth which rotates at 1,000 an hour, revolves around the sun at 66k MPH, which moves around the galaxy at 43K MPH, which moves at 1.3M MPH and rotates at 483K MPH!

When constructing the world's biggest concrete structure, the speed of the earth's rotation slowed down by a fraction. Welcome to the Anthropocene.

Neutron Stars will undergo a sudden increase of rotational speed (called a glitch) due to events called starquakes.

You can outrun the rotational speed of Venus.

B1937+21, the second fastest known pulsar, rotates about 642 time a second. The surface of the star is moving about 1/7 the speed of light. Here is what it sounds like. Wow.

We only see one half of the moon because it rotates on its axis, and revolves around Earth at the same speed.

The 2011 earthquake near Japan increased the Earth's rotation speed, shortening the day by 1.8 microseconds

Lovebirds can rotate their heads at speeds of up to 2,700 degrees per second
