Sun Facts

The Sun is a star that provides light and life to the Earth. It’s solar energy keeps us warm in winter, lights our homes with its natural glow at night, makes plants grow for food production within hours of the sunrise each day, heats oceans for swimming water on hot days and enables this planet’s weather patterns which we all rely upon.

Our Solar System - Sun Facts - Optical

1. Sun is the source of all life on Earth

2. The sun has a diameter of 864,400 miles

3. The sun’s surface temperature is about 10,000 degrees Fahrenheit

4. A solar eclipse happens when the moon blocks out the light from the sun and casts its shadow on Earth

5. Solar eclipses happen every 18 months or so because that is how long it takes for the moon to orbit around Earth

6. The only time you can see a solar eclipse without special glasses is during a total solar eclipse  when there are two full moons in one month and they line up with earth and the sun at just enough distance apart to make this possible a lunar eclipse occurs when it lines up with earth instead of with our own moon the last time this happened was in 1982-1983 but we won’t have another until 2033-2034

Facts about the sun

The sun is a star, and it has many properties that are different from our own. For example, we know for sure that it’s all colors mixed together because of how white they make everything look to us on Earth; this phenomenon appears as various shades of yellow when seen in images taken with infrared light by NASA’s Solar Dynamics Observatory (SDO). The composition: 70% hydrogen and 28% helium – two elements you’re probably familiar with already! This mix gives off an immense amount heat energy which allows life-giving water vapor to form clouds before releasing them into space through evaporation. Even though its surface area seems much larger than ours thanks to being 330 thousand times more massive than the earth itself!

One million Earths could fit inside the Sun

One million Earths could fit inside the Sun. The hollowed-out center of a sun would fit around 960,000 spherical earths. If squished into one with no wasted space, 1,300,000 more spheres might be able to make it in there!

The Sun contains 99.86% of the mass in the Solar System

The Sun is an amazing ball of gas that holds the rest of our Solar System in its grasp. The sun comprises 99% and more than 330,000 times Earth’s weight! Outcomes from a mixture hydrogen and helium with less than 1%.

The Sun is the closest thing to a perfect sphere that has been observed in nature.

The Sun is an almost perfect sphere

It measures 10 kilometres more at its poles than it does along its equator, and this makes for an almost-perfect shape with only minor imperfections.

What happens when the sun consumes Earth?

The Sun has been burning for billions of years, but it will not last forever. When our nearest star is out of Hydrogen and only left with Helium to burn, its gravity would have increased so much that Mercury-Venus-Earth are swallowed up by it! It’s going to be an exciting time in space as this red giant engulfs all three worlds

The Sun will one day be about the size of Earth

After its red giant phase, it’ll shrink down and become a small planet called a white dwarf!

The temperature inside the Sun can reach 15 million degrees Celsius

The atoms are pulled together by the gravitational force of the Sun, but they press against one another with as much energy. The temperature at its core is so high that it reaches 15 million degrees Celsius! Heat and light generated from nuclear fusion can be clearly seen on Earth through a telescope or binoculars – not to mention our sunsets!

The surface of the Sun has a more manageable 5,600 degree celsius.

Light from the Sun takes eight minutes to reach Earth

To comprehend the time it takes light to travel from one object at a distance, all you need is divide 150 million kilometers by 300,000 km/s. That equals 500 seconds (or eight minutes and 20 seconds). It’s taken millions of years for energy emitted form the Sun’s core to reach its surface but once that journey has been made in most cases more than five thousand billion trillion photons will have left their mark on our sun ray-drenched planet Earth.

The Sun travels at 220 kilometres per second

The Sun is 24,000-26,000 light years from the galactic centre. It takes the Sun 225-250 million revolutions to complete an orbit of our galaxy’s center.

The Sun has a very strong magnetic field

The Sun is a giant ball of energy that has been spinning since the beginning. Magnetic storms cause solar flares, which we see as sunspots on Earth’s surface. Solar flare activity can be seen in twisted lines and spiraling patterns akin to earthbound tornadoes
