about 340km above the earth
The same distance as the Earth - it's in low Earth orbit, just a few hundred miles above Earth.
Not very far. The International Space Station is in an orbit about 350 km (217 miles) above the earth's surface ... roughly the distance between Los Angeles and Las Vegas. The moon is about 1,100 times as far away, and the sun is about 425,000 times as far away.
It takes 2 days. You might think that that's a long time for a space shuttle to go to the space station. Especially when you know that it takes about 2 minutes for the space shuttle to go into space. But here's why: The space station is orbiting the earth, and so will the space shuttle when it goes into space. If it goes faster though, it will fly away from the earth's atmosphere and get lost in outer space. So the Space Shuttle goes slightly faster so it will catch up, but not too fast so that it will fly off into outer space. That's why it takes 2 days.
Now that the construction of the International Space Station is complete, the structure measures 108.5 meters by 72.8 meters (356 feet by 239 feet) . . . slightly larger then a full sized soccer field. The completed ISS weighs around 450 tons.
The International Space Station is in a low Earth orbit between 199 mi and 216 mi. To maintain this orbit, the space station has to travel at a speed of about 17,500 miles per hour. If a spacecraft was launched sideways off the Earth with a low velocity, gravity would pull it towards the ground. If the spacecraft was launched at a faster velocity, it would hit the ground at a farther distance because the ground would be curving away at a faster rate. However if the spacecraft was launched fast enough, the Earth would constantly curve away as the spacecraft falls indefinitely. The spacecraft would be in orbit. The speed required for the International Space Station to orbit is 17,500 miles per hour. The higher an object's orbit is, the slower it has to travel to maintain that orbit.

None any further away than the International Space Station yet.

The gravitational pull decreases in inverse proportion to the square of distance from the centre of the earth, thus it would speedily decrease as we go away from earth but never become zero anywhere, it remains, in however small quantities. Say, 160 km from the surface of the earth, the gravitational pull would be 0.95 times that at the surface of the earth (which is 9.81 m/s2). At 400 km from the earth (where the International Space Station seems to be floating), it would be 0.88 times that which is at the surface of the earth. Near moon, it would be .000272 times of what we feel here. Now, the weightlessness they feel on the International Space Station is due to the fact that the Space Station is circling around earth once in 91 minutes. The centrifugal force compensates for the remaining 0.88 g gravity there.
Put away space station and touch word'fuel'
Even though free fall causes objects on the International Space Station to appear to be weightless, there actually is gravity. Gravity gets weaker as you move away from the Earth, although it still exists. The change in gravity can be calculated with the equation: 1/(Radius^2). The Earth is about 4000 miles in radius, so in the equation, 4000 miles would be R=1. At 4000 miles in altitude, the distance to the center of the Earth would be 8000 miles so it would use R=2 (twice the radius of the Earth). At the space station's altitude of 200 miles, the equation would use R=1.05. 1/(1.05^2) equals about .91, so gravity on the space station is about 91% of the gravity on the Earth.
It's both. Travel by humans to anywhere further away than the Moon is, so far, "fake" (or at best speculative). However, the Apollo manned Moon missions were real, as are low Earth orbit missions like those to the International Space Station and the Hubble Telescope.
