Space is Big
An astronomical unit (AU) is the average distance between Earth and the Sun, about 93 million miles. Why do asn000mers use astronomical units to measure distances in space? In what different ways can you compare the distances between objects and the locations of objects using the four mathematical operations?

Watch the STEAM Video ‘Space is Big: Then answer the following questions.

Question 1.
You know the distances between the Sun and each planet. How can you find the minimum and maximum distances between two planets as they rotate around the Sun?
Answer:

Question 2.
‘The table shows the distances of three celestial bodies from Earth. It takes about three days to travel from Earth to the Moon. I low can you estimate the amount of Lime it would take to travel from Earth to the Sun or to Venus?
