... between the sixpence and the sun; and that number will be the number of sixpences required to stretch across the sun, and, knowing the diameter of the sixpence, you know the diameter of the sun. Then, as to the weighing of the sun, this ... to the sun. The water wheel is turned by the sun. Its heat raises the water from the ocean and deposits it in the form of rain on the mountain's side. The river collects the rain, fills the buckets of the water ...

... , the core will begin to cool. This event will throw off the delicate balance between pressure in the core and gravity and result in a sudden collapse of the Sun's outer atmosphere on the core. The collapse will initiate a rise in temperature which will then force additional hydrogen surrounding the Sun ...

... believe that smaller clouds of dust far enough away from the large cloud that became the Sun avoided being pulled in by our new Sun's growing gravity, yet were close enough to be caught in its orbit. Slowly they began to draw themselves together the same way that our Sun did. However, because they were so much smaller and less dense than the dust-cloud that formed the Sun, they did not generate the same intense heat ...

... realized that the Sun could not be powered by any ordinary means like a common fire or it would soon go out The mystery remained until the twentieth century when scientists discovered that the Sun was powered by fusion-the conversion of hydrogen into helium with the enormous release of energy. Nuclear fusion has provided the Sun with enough ...

... Sun is, it would extend all the way out beyond the orbits of Mars and reach the orbit of Jupiter-an astonishing 600 million miles across Now once you understand that fact, and that the Sun is a small stable star with the next closest star over 4.28 light years away, you can easily see that the Sun will have very little influence over the life of the other ...

All life comes from the Sun, so without it, life as we know it would rapidly come to an end. But the good news is that the Sun is a very stable, small star that has existed for a long time and allowed life to gain a foothold on Earth. The Sun will continue ... /For%20Kids/KidstoSpace.html Click here Category:Kids To Space Category:Kids To Space - THE SUN

The Sun is about 872,000 miles across. About 109 Earths could fit across the diameter of the Sun. Because the Sun is a ball of gas, it is slightly distorted and rotates faster at the center than at the poles. This makes it slightly oblate at the equator but for practical purposes in normal discussions, you can consider the Sun to be round. Once again, gravity is the key ...

... as the Earth has a yearly orbit around the Sun, our Sun also orbits the center of our Milky Way Galaxy once every 230 million years. It is amazing to think about the fact that the last time our Sun passed through this area of the ... the solar system orbital motion is a consequence of the motion of the original cloud of gas that formed in this region of space and eventually gravitationally collapsed to form the Sun and all the planets ...

... a particular emphasis on the solar atmosphere - the source of the so-called `space weather'. The results include a rather unexpected feature of the nature of so-called active regions on the Sun, the discovery of new solar phenomena, such as solar tornadoes and jets, a new view of the nature of the quiet Sun, and a new insight into the way the Sun ejects vast clouds ...

... ship that could travel between the Sun and the near stars periodically. Because of the long durations, the spacecraft is assumed to be massive to house many people for many generations. The spacecraft is initially accelerated ... . The spacecraft returns by using gravity to "swing" around each of three or more stars, one of which is the Sun. The minimum distance of closest approach found during the flyby was 3 Sun radii, where the heat flux of 7 MW/m2 was shielded from the spacecraft by a ...
