The Sun is the Solar System: Sun accounts for 99.8% of the mass of the Solar System and earth is just a fraction of the mass
Sun is mostly hydrogen and helium: 74% of its mass is hydrogen and 24% is helium with total of 98%
Sun is pretty bright:Sun would be the 4th brightest star in the universe in absolute terms
Sun is huge but dwarf:You could fit 1.3 million Earths inside the Sun but there are some much bigger stars out there
Sun is huge but dwarf:the biggest star that we know of would almost reach Saturn if it was placed inside the Solar System
Sun is middle-aged:Sun is in the main sequence stage right now but in about 5 billion years from now, the Sun will enter the red giant phase
Sun has layers: Sun looks like a burning ball of fire, but it actually has an internal structure
Sun will kill all life on Earth: in just a billion years, the heat from the Sun will be so intense that Life on Earth as we know it will be gone forever.
outer atmosphere is hotter than the surface:The surface of the Sun reaches temperature of 6,000 Kelvin But above the surface, temperatures can reach 100,000 K.
spacecraft are observing the Sun: SOHO has been continuously observing the Sun since then, and sent back countless images.
Different parts of the Sun rotate at different speeds:Regions at the equator take 25 days to complete one rotation, while features at the poles can take 36 days
Different parts of the Sun rotate at different speeds:The most famous spacecraft sent to observe the Sun is the Solar and Heliospheric Observatory, built by NASA and ESA
