A fact about Sun

It has a mass of around 330,000 times that of Earth. It is three-quarters hydrogen and most of its remaining mass is helium. Over one million Earths could fit inside the Sun. If you were to fill a hollow Sun with spherical Earths, somewhere around 960,000 would fit inside.

What are 2 facts about the sun?

The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.

Why is the sun hot?

The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

What is true sun?

The sun is a big ball of gas and plasma. Most of the gas 91 percent is hydrogen. It is converted into energy in the sun’s core. The energy moves outward through the interior layers, into the sun’s atmosphere, and is released into the solar system as heat and light.

Is the sun hot or cold?

The surface of the sun stays at an incredibly hot temperature of about 5800 Kelvin all year long. The high temperature of the sun causes it to constantly emit prodigious amounts of thermal radiation in all directions, mostly in the form of infrared waves, visible light, and ultraviolet waves.

Is the sun lava or fire?

The sun is a big ball of gas and plasma, but what is the sun made of exactly? Most of the gas — around 92% — is hydrogen, according to NASA. It is converted into energy in the sun’s core.
