The sun is a star, and it is the closest star to Earth, located about 93 million miles away.

The sun is made up of mostly hydrogen (about 74%) and helium (about 24%) gas, with other elements making up the remaining 2%.

The sun is extremely large, with a diameter of about 1.4 million kilometers (870,000 miles), making it 109 times larger than the diameter of Earth.

The sun's energy output is incredibly strong and is the primary source of energy for life on Earth.

 The sun has a complex magnetic field that can cause phenomena like sunspots, solar flares, and coronal mass ejections, which can affect Earth's atmosphere and magnetic field.

The sun rotates on its axis, but not at a uniform rate - different parts of the sun rotate at different speeds, causing its magnetic field to become twisted and tangled over time.

Solar eclipses occur when the moon passes between the Earth and the sun, casting a shadow on Earth and temporarily blocking the sun's light.

The sun is estimated to be about 4.6 billion years old and is about halfway through its expected lifespan.

The sun's corona, or outer atmosphere, is much hotter than its surface, with temperatures reaching millions of degrees Celsius.

Sunlight takes about 8 minutes and 20 seconds to reach Earth, traveling at a speed of about 299,792 kilometers per second (186,282 miles per second).
