The Sun

The Sun might look uneventful in visible light, but viewing the Sun in ultraviolet light shows  its active coronal loops.These are jets of plasma  that follow the Sun’s magnetic field.In addition to showing the turbulent surface of the Sun, it also shows the planet Venus crossing in front of the  sun near the end of the Sun.

 

The Sun lies at the heart of the solar system,where it is by far the biggest object.It holds 99.8 percent 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.The visible part of the sun is about 10,000 degrees Fahrenheit while temperatures in the core reach more then 27 million Fahrenheit driven by nuclear reactions.One would need to explode 100 billion tons of dynamite every second to match the energy produced by the Sun,accoring to NASA.
