If there is a street for sky, so it will take seventy years to walk for a human being.
How many sky in the univers
In real sense, there is no sky, what we see in actual sense is the space.
The sky isn't necessarily there, the blue factor of the sky is created when all of the Earth's water reflects off the sun, and bounces back to Earth. So the sky is kind of like a mirage: you can see it but its not really there. Therefor since it is not there, there is no distance from the Earth to the sky.
Distance from Earth.
The sky is over the entire earth. it is the same distance from the north pole as it is the south.
Your place on the earth, The brightness of the star, Its distance.
Earth's moon ... the one you see in the sky from your backyard ... does not circle Mars.The distance from earth to our moon is less than 1/2 percent of the closest possible distance from earth to Mars.
The birds flying in the sky do not cast their shadow on the earth because the umbra is absent and the penumbra is too large and too faint that it is not visible as the distance of the earth is very large from the bird.
"Libra" is a constellation ... a group of stars that seem to join in a pattern when viewed by humans on Earth, in a region of the sky defined by human astronomers on Earth. The stars in Libra are totally unrelated to each other, and each of them is at a different distance from Earth.
Muchi, bus la irrunthu kela velura thoramdhan.
The sky is the Earth's atmosphere.It is not above you, you are in it.
Constellations don't have a particular distance from Earth. This is because the stars only APPEAR to be a group in the sky. In fact they are all at different distances usually.
