Escape velocity In common usage, the initial point is on the surface of a planet or moon. On the surface of the Earth, the escape velocity is about 11.2 kilometers per second (~6.96 mi/s), which is approximately 33 times the speed of sound (Mach 33) and several times the muzzle velocity of a rifle bullet (up to 1.7 km/s). However, at 9,000 km altitude in space, it is slightly less than 7.1 km/s.

The Earth Nevertheless, the diameter of the Earth still is the first step for us, the residents of this planet, in our attempt to understand the cosmic distance scale. Travel Time The Space Shuttle orbiter, with a velocity of 27,880 km per hour (17,322 miles per hour) takes approximately 90 minutes to orbit, or travel just outside the circumference of the Earth.

Geostationary orbit A geostationary orbit can be achieved only at an altitude very close to 35,786 km (22,236 mi) and directly above the equator. This equates to an orbital velocity of 3.07 km/s (1.91 mi/s) and an orbital period of 1,436 minutes, which equates to almost exactly one sidereal day (23.934461223 hours).

What is the distance (in miles) the earth travels round the Sun?. One round trip.? Therefore in one year the Earth travels a distance of 2*pi*(149,597,890)km. This means that the velocity is about: velocity=2*pi*(149,597,890)km/1 year. and if we convert that to more meaningful units (knowing there is 365 days in a year, and 24 hours per day) we get:

Escape velocity For an actual escape orbit a spacecraft is first placed in low Earth orbit (160–2,000 km) and then accelerated to the escape velocity at that altitude, which is a little less — about 10.9 km/s.or an object of mass the energy required to escape the Earth's gravitational field is GMm / r, a function of the object's mass (where r is the radius of the Earth, G is the gravitational constant, and M is the mass of the Earth, M =5.9736×10 24 kg).

The Orbital Velocities of the Planets The orbital velocity is 2πR/T where R is the average radius of the orbit and T is the length of the year. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year.

How Fast Does Earth Move Through The Universe? The Earth spinning on its axis gives us a speed of just 0.5 km/s, hardly a blip on our radar when you compare it to all our other motions. The Earth, you see, much like all the planets in our Solar System, orbits the Sun at a much speedier clip. In order to keep us in our stable orbit where we are, we need to move at right around 30 km/s.

- To orbit the Earth you have to go FAST, for low orbits about 17,500 mph. If you launch to the east you get boost from the Earth's rotation. For launches near the equator that boost is about 1,000 mph. My favorite bit of evidence is a bit subtle.

The Orbital Velocities of the Planets This means that in 365.25 days the Earth travels 587.5 million miles. This works out to about 67 thousand miles per hour. This is the speed we travel 24 hours a day, 365.25 days a year. The orbital velocity is 2πR/T where R is the average radius of the orbit and T is the length of the year. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year.

Earth's mean orbital speed Earth's mean orbital speed is the average speed at which the Earth revolves around the sun. This is defined in two different ways, based on the sidereal year and the tropical year.The sidereal year is the time it takes for the Earth to revolve once around the sun with respect to the distant stars.herefore, the circumference is about 9.399511 x 10 11 m. The Earth's mean orbital speed, in meters per second (m/s), is obtained by dividing this number by the length of the year in seconds.

Couldn't I escape Earth's gravity traveling only 1 mph (0.45 m/s)? It is said that in order for an object or a projectile to leave Earth's gravitational pull, it must reach Earth's escape velocity, meaning reach a speed of 7 miles per second (~11 km per second).

How does the ISS orbit the earth? For the ISS, at an altitude of about 250 miles (400 km), that forward velocity is about 17,500 mph (7.8 km/s). For a circular orbit, the equation to figure out what the appropriate velocity would be, is: Where G is the gravitational constant. M is the mass of the body being orbited (Earth).

- The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). A satellite at this height takes 12 hours to complete an orbit. As the satellite moves, the Earth rotates underneath it.

- The Moon's orbital velocity is about 1 km/sec, so its shadow travels at that same velocity. While the Earth's rotation also proceeds from west to east, the FASTEST motion generated by that rotation is at the equator and works out to less than .5 km/sec.

Escape velocity For other uses, see Escape velocity (disambiguation). In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from Earth is about 40,270 km/h (25,020 mph). More generally, escape velocity is the speed at which the sum of an object's kinetic energy and its gravitational potential energy is equal to zero.

Speed Needed to Escape the Earth (Escape Velocity) The velocity of escape from the Earth's surface is about 11.2 km/s.. 11.2 km/s. Space travel is something we may now take for granted, but there are many factors we first have to look into. One thing we have to do is overcome the force of gravity holding us down.

Why is geosynchronous orbit an altitude, rather than a velocity? A slightly higher orbit might take 100 minutes instead of 90. For a geosynchronous orbit, the orbit has to take 24 hours instead of 90 minutes, because the earth takes 24 hours to spin. This happens when the circle is expanded to an altitude of about 35000 km. The Goldilocks velocity at this altitude is about 3000 m/s.
