The Sun ⛅is a 4.5 billion year old yellow dwarf, a hot, glowing  hydrogen and helium sphere in the heart of our solar system. It is about 150 million kilometers from Earth and is the only star in our solar system. Without the energy of the sun, life as we know it could not exist on our home planet. 
From our vantage point on Earth, the Sun may emerge as a constant source of light and heat in the sky☁️. However, the Sun is a dynamic star🌟 that constantly changes and sends energy  into space. The science of studying its effects on the Sun and  the entire solar system is called solar physics.⚛️ 
The sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). Its gravity holds the solar system together, keeping everything from the largest planet to the smallest  debris in orbit around it. The 
 Sun is the center of our solar system and essential to our survival, but it is only an average-sized ✨. Stars up to 100 times larger have been discovered. And many solar systems have multiple stars. By studying our Sun, scientists can better understand how distant stars work. 
The hottest part of the sun is its center, with temperatures 🌡️above 15 million ° C (27 million ° F). The photosphere, which is the part of the sun that we call its surface, is  relatively cool at 5,500 ° C. One of the sun's greatest mysteries,  the corona, gets hotter away from the surface. The corona can reach up to 2 million ° C (3.5 million ° F). This is much hotter than the photosphere.

Origin of the name 
The sun has been called by many names. The Latin word for the sun is sol. This is the main adjective for everything related to the sun🌞. It's the sun. Helios, the sun god of ancient Greek mythology, is also the name of many terms related to the sun, such as the heliosphere and helioseismology. 
Possibility of life 
Due to its extreme temperature and radiation, the sun could not support life as we know it. But life on earth is possible only by the light and energy of the sun. 
size and distance 
Our Sun is a medium-sized star with a radius of about 435,000 miles (700,000 kilometers). Many stars are much larger, but the Sun is much larger than our home planet. It takes more than 330,000 Earths to be equal to the mass of the Sun, and  1.3 million Earths 🌎to fill the volume.

Thank you ✨ save our planet🍃
