The first American space station, Skylab, fell to earth in 1979.
It would fall to Earth's surface.
Objects fall to the ground due to gravity, which is a force that pulls objects toward each other. However, in microgravity environments like the International Space Station, objects appear to float because they are in constant free fall around the Earth.
The most meaningful answer is zero G. You, the space-station and everything in it are in free-fall towards Earth. All are 'weightless' (but not massless).
An apple falling from a tree is an example of an object in free fall.
No. The "weight" of the Earth is a meaningless concept, because the Earth is in free-fall, in orbit around the Sun. How much does an astronaut in the International Space Station weigh? Nothing; he's "weightless", in free orbit. Same with the Earth itself. The MASS of the Earth is actually increasing by a few hundred tons each day, as meteorites and cosmic dust fall into the Earth's gravity well.
An object is weightless when it is in free fall, such as when an astronaut is orbiting the Earth in the International Space Station. In this situation, the object is technically still affected by gravity but experiences a sensation of weightlessness because it is falling at the same rate as its surroundings.
It depends on how close you are in your orbit. The international space station is about as close as you can get in free fall orbit, orbiting once every hour and a half or so. As you go further out the time taken increases. The moon is quite far out, orbiting earth once a month.
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.
The ISS is used for various research projects and experiments that can only be performed in micro-gravity. (free-fall, or zero G)
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
