The surface area of the Sun is 11,990 times that of Earth. (1,300,000 Earths would fit inside the Sun!!) Let's write 11,990 in expanded form.
10,000 + 1,000 + 900 + 90 + 0
One orbital period (one year) on Mercury is 88 Earth days. How many Earth days would equal 3 years on Mercury?
264 Earth days would be 3 years on Mercury!
Fun Fact: Mercury is the closest planet to the sun.
One year on Jupiter is like 12 years on Earth, because it is so far away from the sun and takes longer to go around the sun. How many Earth years make up 4 Jupiter years?
