What are the facts about the sun?

Answer 1

• The Sun's diameter is about 870,000 miles wide.
• The Sun is 109 times wider than Earth, and is 333,000 times heavier. That means if you put the Sun on a scale, you would need 333,000 objects that weigh as much as the Earth on the other side to make it balance.
• The Sun is only one of over 100 billion stars.
• Over one million Earths could fit inside the Sun.
• Looking directly at the Sun can permanently damage your eyes because it is so bright.
• The Sun is a star. A star mostly gives off light and heat. The larger the star, the hotter its temperature.
• A super giant star can get to be 400 times larger than our Sun, which is almost a million miles in diameter.
• The Sun is tilted at an angle.
• The mass of the Sun is 1.98892 x 1030 kg. The sun takes up 99.8% of the Solar System's Mass. Therefore the mass of the rest of the solar system including planets is 1.99 x 1028 or 0.2% the mass of the solar system.
• The temperature at the center of the Sun is approximately 15,000,000, degrees C.
• The Sun is, at present, about 70% hydrogen and 28% helium by mass. Everything else ("metals") amounts to less than 2%.

Answer 2

Although its energy output is immense, the average energy-per-unit-volume of the Sun is less than that of a human being.

The Sun is just a star, but it is the closest one to us, and it formed along with the planets and other solar system objects (asteroids, meteroids, comets).

The Sun is 10 times the size of the largest planet (Jupiter) and contains 98% of the mass of the solar system. The Sun has the same volume as 3 million Earths.

As active stars go, the Sun is not very large. But it is among only 15% of all stars to be in an active phase, the rest being red dwarfs or smaller forms.

The Sun accounts for 99.86% of the Solar System's mass. It is still mostly hydrogen and helium, the surface composition being 75% and 24% respectively. Heavier elements are found in a comparatively tiny area near the center.

The core of the Sun is extraordinarily dense and hot, about 15 million kelvins, but the surface is "only" about 5800 K (5500 °C). The hottest molecules are located above the surface in the corona, and can be as hot as 20 million kelvins. This is partly from the effect of extreme magnetic fields.

Answer 3

The sun is the biggest thing in the solar system with a diameter of 865,000 miles across (1,390,000 km) the sun is one of the biggest things that keeps us alive from its heat. the sun is so powerful that every day it wastes about 1 trillion atomic bomb energy a day that is so great. The sun has no solid surface and and burns helium into hydrogen we are lucky that the sun is this big because it is the perfect! size to burn the sun is 80 times bigger then the biggest planet in the solar system Jupiter its magnetic pull is powerful enough to hold 8 planets and about 152 moons. In 5 billion years doomsday for the sun will come because the sun will become so hot with a temperature of 1 billion degrees and will grow 200 times bigger will destroy the 3 inner planets Mercury, venus, earth and maybe mars and will explode making it a dead star the size of earth.
