There's no precise answer to the question of "Where does space start?"
But you might consider it to be the distance far enough off the surface of the earth where artificial satellites can survive in orbit ... meaning the altitude where the atmosphere has thinned out sufficiently so that atmospheric drag is essentially negligible. This places us in the neighborhood of the orbital altitude of the International Space Station, which is a significant milestone; so in order to be able to offer a figure for negotiation, let's say ...
Space begins at roughly 220 kilometers (140 miles) from the earth's surface.
the north star. it takes 8 minutes for light to get from the sun to the earth. it takes half a billion years for light to get to us from the north star...i think. but i know that the sun is definetly closer.
No. To start off, the sun is a star, not a planet and is far larger than any planet. The sun is larger than the average star, but it is nowhere near being the largest.
Neither. It is actually a star. Its true name is Polaris, just as the true name of the sun is Sol. It is nicknamed the North Star because it is the only star that appears not to move in the sky, because its position is directly over the North Pole.

The North Star does not orbit the sun, nor do any of the stars. The North Star is its own star system several times more massive than the sun.
Do You Know That The Sun Is How Far From Main Sequence Or Called White Dwarfs .. The Sun Is Our Star And It's Size Is Medium-Sized The Far As 8,400 Solar Radii In Sun ,,

No. Mercury is one of the planets that orbit the sun. The North Star is Polaris.
The Sun is by far the nearest star to Jupiter.
Barnard's star is about 6 light years away from the sun.
a star is a big ball of hot gas just like our sun. infact a star is a far off sun somewhere in our universe.

That's not possible a star is a sun, planets revolve around a star, and the planet would be destroyed far far far far far before the star reached it, if that was even possible
No. The sun is a main sequence star far smaller than any supergiant.
They are the same thing. A sun is right here, while a star is VERY far away. But if we could build - WHEN we CAN build! - interstellar spacecraft, we will take off from the Earth, and we'll see our Sun nearby. When we get there, we will find a new sun in the sky - and our Sun will be a tiny star, far away!
