none ,there isnt any
we all die
A rock. If it hits the Earth's atmosphere and we see it, it will be a "meteor". When it lands on the Earth, it will be a "meteorite".
This depends upon how much fuel you are prepared to burn to oppose the force of gravity. Even the ordinary satellites are falling towards the Earth, and require a periodic thrust (burn) to keep them in orbit. Unfortunately, the attraction due to gravity depends on mass, so most of the space junk just stays up there, whereas the orbiting satellites need an occasional burn to keep them there.
The chances are pretty low because it doesn't matter on the size to detect gravity.
Simple! they send people to space to investigate space! The moon is an example! people are sent there to check out the moon, to find theories and discoveries. An example of a discovery: the moon was a meteorite that hit Earth , and been orbiting Earth by Earths gravitational force. they must have found that out by its craters or something! They could have also measured how much gravity is in moon.
Not at all. The mass of the spacecraft affects how much fuel it takes to boost it into the desired orbit, but the mass has no bearing on the orbit itself. Examples: A "spacewalking" astronaut, hovering a few inches off the skin of the Space Shuttle. The astronaut has much less mass than the shuttle, but both of them are in the same earth orbit. A piece of "space junk" that's still up there orbiting the earth. Maybe it's a bolt that weighed a pound before it was launched as a part of a large rocket. It certainly has less mass than the earth has, but both the bolt and the earth are in the same orbit around the sun!
No. The mass of the sun is much larger than the mass of the earth, so the earth is regarded as orbiting around the sun.
yes earth is much different than space because space has no air or water.
A lot. you can find junk and rock satillite parts and maybe even a camera!
No there are no satellites that the space program can reuse. This is why there is so much space and orbital debris in the solar system. Space and orbital debris means space and orbital junk or pollution.
The mass of the earth is over 80 times the mass of the moon. A massive object will tend to capture less massive objects in its gravitational field.____________But consider this: if the moon happened to be the same general size and mass as earth, which would orbit which? You would observe them each orbiting around an invisible spot half way between them, their 'system' center of gravity otherwise called the 'barycenter'. They would effectively be orbiting around each other. As the moon becomes less massive, what determines the 'cut-off' between orbiting around each other and the smaller orbiting the larger? In fact it is still true that earth and moon are each orbiting their barycenter. Interestingly, the barycenter in this case is within the body of the earth, because the earth is so much more massive than the earth.
The mass of the Earth is about 5.97 times 10 to the 24th power kilograms. The Earth has no weight, because it is orbiting in 'free fall' around the Sun. Like other objects in space, the Earth is weightless. Weight is measured as the force of gravity pulling an object toward a much larger object's center. (Like the center of the Earth, the center of the Moon, the center of Pluto, and so on)
