Yes. Earth's gravity is still very present at 36,000 km. This is what keeps geosynchronous satellites in orbit. Earth is the dominant gravitational body much farther out than that, to a distance of about 1.5 million km. Beyond that distance there is still gravity, but the sun, not Earth, dominates.

What altitude is the pressure in earth's atmosphere equal to that of mars?
The pressure in Earth's atmosphere is roughly equal to that of Mars at an altitude of about 30 kilometers (18.6 miles) above sea level. This means that if you were at this altitude on Earth, you would experience a similar atmospheric pressure to that on the surface of Mars.
How many circumference of the earth at the equator is approximately how long in kms?
40,073 km
How far are greenhouse gases from the surface of the earth?
Greenhouse gasses are all around us. In fact, you breathe out carbon dioxide every time you exhale, and when you drink water, you're conusming H2O, which in vapor form is also a greenhouse gas.
Does the earth orbit twice as fast as mars?
Not quite exactly, or nowhere-near, depending on what you mean by "how fast".Period of orbitEarth . . . 365.26 earth-daysMars. . . . 686.97 earth-daysThe Earth takes 53.2% as long as Mars does to orbit the sun. But that's "orbiting about twice as frequently", not "orbiting twice as fast".Average orbital speedEarth . . . 29.8 kms-1Mars. . . . 24.1 kms-1Earth only moves 26% faster than Mars in its orbit.
What is the Venus size?
Venus has a diameter of about 12,104 kilometers, which is similar to Earth's diameter. It is sometimes called Earth's "sister planet" due to its similar size and proximity to our planet in the solar system.
How long would it take to travel from earth to Venus at a rate of 36000 kilometers per second?
This depends completely on how close Venus is to the Earth as they have different orbital periods and so the distance between varies greatly. Currently Venus is approximately 2.421 x 108 km from Earth as of 06 November 2009. At 36000 kms-1 it would taken around 1 hour 52 minutes to travel this distance.
How far do you travel for a one hour time change?
We travel about 1670.45 kms per hour relative to the space. Earth takes full circle in 24 hrs. So total distance covered in 24 hrs by any body present on the surface of the earth is equal to the circumference of the earth, which is 2*pi*r where "r" the radius of earth is 6378.1 kms.
What is the escape velocity from the surface of Mars?
The escape velocity from the surface of Mars is about 5.0 km/s (3.1 miles/s). This means that a spacecraft would need to reach this speed to break free from Mars' gravity and enter into space.
If you fall 12 756.2 kilometers with gravity how fast would you be going after the fall?
You don't fall when you are at a height of 12756.2 kms above the sea level because you are in space. Depending on the meagre gravity exerted by earth, you will descend slowly. May be when you cross earth's orbit and enter the atmospheric layer, your speed might increase but it will not be vertical fall.
How high does a rocket have to go above Earth's surface until its weight is half what it would be on Earth?
The mass of an object at any point will remain the same( unless its velocity approaches that of light, of course )So, for the weight to reduce to half its value, the acceleration due to gravity has to reduce to half its value on earth. now, the relation between acceleration due to gravity and distance from the center of the earth is given by g = 1/R2 where R is the radius of the earth which is 6400 kms (approx) let 'h' be the height at which the weight of the rocket will be half its initial value. so, gh / g = R2 / (R+h)2 but gh = g/ 2 substituting it in the above expression yields h=2649.6 kms (approx) so, at this height, the weight of the rocket will be half its initial weight.
How far is Lisbon from Fatima?
According to Google Earth, 128 kms.
How many square kilometres of earth is tundra?
About one fifth of the earth's land is Tundra, as the Earth has about 57.5 million square miles (149 million sq kms) of land. This is around 11.5 million sq miles (29.8 million sq kms).
How far is it from Bristol to lisbon?
According to Google Earth 2.089 kms by road.
How far apart are Lisbon and Helsinki?
According to Google Earth 4.089 kms
What altitude is the pressure in earth's atmosphere equal to that of mars?
The pressure in Earth's atmosphere is roughly equal to that of Mars at an altitude of about 30 kilometers (18.6 miles) above sea level. This means that if you were at this altitude on Earth, you would experience a similar atmospheric pressure to that on the surface of Mars.
What is the kms diameter of the earth?
The diameter of the Earth at the Equator is 12756.2 km The Polar diameter is slightly less - 12713.6 km
How fast do you have to travel on the earth to keep up with the sun?
6 billion kms an hour
