- 3207 - VELOCITY - Earth is moving how fast? For humans standing on the surface of our planet, they don't feel Earth hurtling around the sun because they're also hurtling around the sun at the same speed.
-------------------------- 3207 - VELOCITY - Earth is moving how fast?
- As sure as night turns into day you know the Earth is moving, right? Do you know how fast?
-
- And as sure as July turns into January the Earth is moving around the Sun.
-
- Earth is constantly moving. Not just in ur solar system but in our galaxy and even in the Universe.
-
- Earth also spins on its axis. So, how fast is Earth moving? That should be easy to figure out. We have a 24 hour in a complete day. And the Earth is 25,000 miles in diameter.
-
- How fast is it rotating on its axis and how fast is it orbiting the sun? How fast is the solar system orbiting the Milky Way galaxy?
-
- Earth turns on its own axis about once every 24 hours (or, to be precise, every 23 hours, 56 minutes and 4 seconds). Earth measures 24,898 miles in circumference. Divide distance by time, the planet is spinning 1,037 mph.
-
- Earth orbits the sun at about 67,000 mph , the distance Earth travels around the sun dividing it by the length of time Earth takes to complete one orbit (about 365 days).
-
- To calculate Earth's distance around the sun, all scientists need to do is to determine the circumference of a circle. We know that the Earth is, on average, about 93 million miles away from the sun, and we know that it travels in a generally circular path (it's actually more elliptical, but it's simpler to do this equation with a circle).
-
- That distance between the sun and Earth is the radius of the circle. To get the circumference of that circle, the equation is 2*pi*radius, or 2*3.14*93 million miles. Once the circumference (the distance Earth travels around the sun in one orbit) is calculated, its orbital speed can be determined.
-
- The solar system, which includes our sun and all of the objects that orbit it, is also moving; it's located within the Milky Way, which orbits around the galaxy's center.
-
- We know that the Milky Way is orbiting a galactic center based on observations of other stars. If stars very far away seem to be moving, that's because the solar system is moving compared with the relative position of those far away stars.
-
- Measuring other stars' movements relative to the sun, scientists have determined that the solar system orbits the Milky Way's galactic center at about 447,000 mph. I bet you did not know you were moving that fast.
-
- Then there's the entire Milky Way, which is pulled in different directions by other massive structures, such as other galaxies and galaxy clusters. Just like we can tell that the solar system is moving based on the relative movement of other stars, they can use the relative movement of other galaxies to determine how fast the Milky Way is moving through the universe.
-
- Even though everything is moving all the time, living organisms on Earth's surface don't feel it for the same reason passengers on an airplane don't feel themselves zipping through the air at hundreds of miles an hour. When the plane lifts off, passengers feel the plane's acceleration as it speeds down the runway and lifts off; that weighted feeling is caused by the plane's quickly changing speed. But once the plane is flying at cruising altitude, passengers won't feel the speed of hundreds of miles per hour because the speed doesn't change.
-
- The passengers won't feel the speed because those passengers are actually moving at the same speed and direction, or velocity, as the airplane. There's no relative motion, everyone sitting on the airplane is moving at the same speed as the airplane itself. The only way passengers might notice their and the plane's movement is by looking out the window at the passing landscape.
-
- For humans standing on the surface of our planet, they don't feel Earth hurtling around the sun because they're also hurtling around the sun at the same speed. --other reviews:

- 2992 - VELOCITIES - the Universe in motion? Everything in the Universe is in motion. It gets more complicated than you can imagine. Let’s start with our Milky Way and work our way around the Universe.
-
- 2413 - One of the slowest velocities we are experiencing is the movement of the Pacific Tectonic Plate. The Pacific Plate is moving at 4 inches per year. That is equivalent to .00000000709 miles per hour. Over 100 million years this velocity moved Bodega Bay Head the full distance of the Pacific coast from Baja Peninsula in Mexico to where it sits today, just 30 miles west of Santa Rosa, California.
-
- 2294 - Velocity - Your motion in the Universe? It is more complicated than you can imagine. And, it is all relative. Motion is where you are to where you get to divided by the time it takes. Each of those variables depends on “Relativity“.
-
- 2180 - Velocity is Space divided by Time. Distances to objects in the Universe refer to their value TODAY, not the time when their light was emitted. The space between galaxies is getting bigger because the Universe is expanding in all directions. Light traveling through space is being stretched by this expansion. Stretched light means it grows in longer wavelengths, lower frequency.
-
- Velocity is space / time. The only thing going faster than light is the expansion of space itself. Today the edge of the Observable Universe is 45 billion lightyears away even though the Universe is only 13.7 billion years old. Those galaxies “appear” to be traveling faster than light because the space between us is expanding.
