kandy V of Azerbaijan asks...
How hot is the sun????
The Sun's core is about 27 million degrees Fahrenheit (15 million degrees Celsius).
The Sun is the largest and most massive object in the solar system. If the Sun were as tall as a typical front door, Earth would be about the size of a nickel.
It is about 93 million miles (149.5 million km) from Earth. That distance is called an astronomical unit, or 1 AU, and is used to measure distances throughout the solar system. The Sun's light and heat takes about eight minutes to reach us, which leads to another way to state the distance to the sun: 8 light-minutes.
The Sun is the center of our solar system and makes up 99.8 percent of the mass of the entire solar system.
