Some very wise man noticed that the shadow cast from a stick placed vertically in the ground was a different angle at exactly noon than the angle of shadow cast at exactly noon from a vertically placed stick in the ground at a location further north. By employing mathematics, he was able to deduce that the earth is in fact, roundish.

How many planes face in sphere?
A sphere has no plane surface. But if we consider a infinitesimal small surface of sphere then we have a plane surface and this way we have infinite planes on the sphere. Let us take the example of earth: earth is a large sphere and to human beings, so small as compared to earth, earth looks like a plane surface which is actually not reality. The same case is with the circle, circle is a closed figure which has no sides but in other way it can be considered as a polygon of infinite sides.
What sphere do you live in?
The sphere that we all live on is called the Earth. (It is not a perfect sphere, but close enough)
Data is sent to earth from satellites using what type of numbers?
Data is sent to earth from satellites using TIROS. This is data given from the ground.
When was the sphere invented?
The sphere wasn't invented, it was natural, like the Earth is natural
Formula to find out the Earth's surface area?
The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

What is meant by a celestial globe?
The Celestial Globe (or sphere) is an imaginary sphere around our planet, earth. All objects in the sky and space, such as satellites, can be thought inside this invisible sphere.
Can artificial satellites prove that the Earth is a sphere?
Not really. They can't even see the entire Earth, because a sphere isn't fully visible from any perspective at any distance. It isn't a sphere anyway - it's an oblate spheroid.

What are the artificial satellites of the Earth?
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
You are part of which sphere of Earth?

What is differences between space satellite and earth satellite?
space satellites are in space and earth satellites are in earth.
Why do gps receive signals from four different satellites?
For accuracy. 1 satellite can only tell you the distance from that satellite (a 3-d sphere around it). 2 satellites can only tell you what your distance from the two of them are(a 2-d circle between them). 3 satellites can give you 2 single points (1 one the surface of Earth, and one out in the middle of space, and they assume you are on Earth when using GPS). 4 satellites is to give extra accuracy on that point that you are at (4 times as accurate as 3 satellites).
Does the earth have two satellites or Mars?
Mars has two natural satellites. Earth has one.
