Our sun what type of star

The first ever stars, made from pure hydrogen and helium are Population III. These exploded as supernovae, producing fusing the lighter elements into heavier and heavier elements. Our Sun, then, contains the metal from previous generations of stars that went supernova. For the quick answer, the Sun is a Population I yellow dwarf star, in the main sequence. Why is the Sun yellow? If you saw it from space, it would actually look white.

I love your advice about earth and wish that I would become the greatest scientist in the world but I know that it will not happen know because I an still young so anyways thank you for helping me on my studies you are a very nice website creator even if I do not know you or seen your face thanks once again!!!!!!!!!

Nothing could live on the Sun, but its energy is vital for most life on Earth. Kid-Friendly Sun The Sun is a star. The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy beyond. Full Moon Guide: October - November Full Moon Guide: September - October Models and lab tests suggest the asteroid could be venting sodium vapor as it orbits close to the Sun, explaining its increase in brightness.

The images show Venus approaching from the left while the Sun is off-camera to the upper right. New research led by NASA provides a closer look at a nearby star thought to resemble our Sun when it was much younger. For its efforts to untangle the long-standing mysteries of the Sun, the Parker Solar Probe team has earned a major award.

This composite image made from seven frames shows the space station in silhouette as it transits the Sun on June 25, Space Station Transits the Sun. A partial solar eclipse over the U. Capitol on June 10, , as seen from Arlington, Virginia. Partial Solar Eclipse over the U.

The Sun has revealed new clues that could help scientists solve the mystery of what causes its powerful and unpredictable eruptions. On Feb. In Voyager 1 became the first spacecraft to enter interstellar space.

Now, it's yielding new insights into what that frontier is like. This was the first direct measurement of the Venusian atmosphere in nearly 30 years — and it looks quite different from Venus past. A suite of scientific balloons is about to lift off carrying instruments that will help scientists understand the connection between the Sun and Earth.

It is one of many stars which shine throughout the galaxy known as the Milky Way. The dwarf sun burns very hot and its central temperature has been estimated to be more than fifteen million degrees Celsius. Nuclear activity takes place within the sun.

At its core, nuclear fusion transforms hyrdrogen. The result is helium. This nuclear activity sends its radiation all the way to the surface of the sun and then travels further into space.

The radiations produced are both light and heat. Light and heat are well-known forms of solar radiation on which we depend on the planet Earth but they are not the only forms of radiation which emanate from the sun. There are quite a few others including radio waves, X-rays and ultra-violet rays. The atmosphere of the planet shields life on Earth from any damaging effects which might otherwise be caused by these forms of radiation.

The sun is a massive star.
