Our Sun's surface temperature is 10,000
degrees fahrenheit or 5,500 degrees Celcius and it's central
temperature is 27 million degrees farenheit or 15 million degrees
Celcicus. The suns mass is 330,000 times the Earths mass.
Our Sun is 5 billion years old. The Sun is made of 70% hydrogen, 28%
helium, and 2% other materials. Our Sun is so big it could fit 900
Jupiters in side if it was hollow. The Sun's diameter is 864,000
miles or 1,390,000 kilometers.
Did you know that the Sun has an atmosphere? There are 2 different
parts of the atmosphere called the chromosphere and the corona. The
chromosphere is the inner layer of the atmosphere, and is even hotter
than the photosphere which is the surface of the Sun. Did you know that
the corona is the outer layer of the atmosphere and it goes millions of
miles out into space? You can only see the Sun's atmosphere in a solar
eclipse, when the moon is blocking the Sun.
Our Sun has things called sunspots, they are cooler than the rest of
the photosphere. Sunspots can be from 600 miles or 1,000
kilometers to tens of thousands of miles wide. Sunspots seem to
be more visible around every 11 years, they are cooler spots on the Sun
and from Earth they appear like darker spots that look black with an
outer brownish layer.
Did you know that it takes the light from our Sun 8 minutes to get to the Earth?
