The sun is a medium-sized star --- if it were as big as a ping pong ball, VY Canis Majoris would be almost as big as a football field
The sun is constantly losing weight --- every year the sun loses 360 million tons
If sound could travel through empty space, the sun would be louder than a train horn about one meter away (125 decibels)
The sun is 330,330 times larger than the Earth
The sun is not a giant ball of fire. It is a ball of plasma with the process of nuclear fusion turning hydrogen into helium inside of its core.
The sun is productive of so much energy that what hits the Earth every hour equals more energy than we use in a year
The sun appears to be the same size as the moon because the moon is 400 times smaller, but also 400 times closer.
If the sun were the size of a cell, the Milky Way would be the size of the United States
Earth is so far from the sun that if it were a pin head and the sun were a soccer ball on the goal line of a football field, it would be 26 yards away
The Sun's diameter is 1,390,000km (865,000 miles)
The sun is continually growing larger and brighter --- In 7.6 billion years, it will reach its maximum size and will shine 3,000 times brighter
Eclipses are possible because of the incredible coincidence that the moon is 1/400th the size of the sun but also 1/400th the distance from earth
The sun is enormous --- 1,300,000 Earths can fit inside of it
Earth is actually located inside the sun's atmosphere
The sun is approximately 15 million C (27 million F) at its center
If the Earth were the size of a pin head, the sun would be the size of a soccer ball
Light is actually pretty slow --- It takes 8 minutes, 19 seconds for light to travel from the Sun to the Earth
The sun is a medium-sized star among the hundreds of billions of stars in the Milky Way galaxy
the sun is not a giant ball of fire, but a ball of plasma with the process of nuclear fusion turning hydrogen into helium inside of its core.
The sun's atmosphere is 300 times hotter than its surface.
