Things You Might Not Know About Our Sun

The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun’s intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Impress Your Friends with These Sun Facts:

If the sun were as tall as a typical front door, the Earth would be the size of a U.S. nickel

The temperature at the sun’s core is about 27 million degrees Fahrenheit

Our sun is more massive than the average star in its neighborhood. Nearly 90% of stars are less massive, making them cooler and dimmer

The sun contains 99.9% of all matter in our solar system

During a single second, the sun converts 4 million tons of matter to pure energy

It would take about 1 million Earths to fill the sun if it were a hollow ball

The sun rotates on its axis approximately once every 27 days

The sun is 93 million miles away from Earth and is almost 5 billion years old

Hubble Sees Saturn - 2007

IC 410 nebula

Pictured above is the IC 410 nebula, a brilliant cosmic dust cloud located approximately 10,000 light years from Earth in the direction of the Auriga constellation. A 4 million year-old galactic star cluster—a region of active star formation—lies toward the center of the image, partially obscured by the nebula itself.

Off to the lower right, two dusty entrails resemble tadpoles. The “heads” of these cosmic squiggles have been sculpted by winds and radiation emanating from the central star cluster. It’s a magnificent sight to behold—even on a primitive 21st century computer screen. (Source)
