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.
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

From an excellent post by Jason Davis
From Washington, D.C., the rings would only fill a portion of the sky, but appear striking nonetheless. Here, we see them at sunrise.
From Guatemala, only 14 degrees above the equator, the rings would begin to stretch across the horizon. Their reflected light would make the moon much brighter.
From Earth’s equator, Saturn’s rings would be viewed edge-on, appearing as a thin, bright line bisecting the sky.
At the March and September equinoxes, the Sun would be positioned directly over the rings, casting a dramatic shadow at the equator.
At midnight at the Tropic of Capricorn, which sits at 23 degrees south latitude, the Earth casts a shadow over the middle of the rings, while the outer portions remain lit.
