Question

Saturn is approximately 1.5 billion kilometers from the sun. What is this distance in AU?

0.1 AU

10 AU

100 AU

1,000 AU

Answer 1

Well, ... how far is an AU, astronomical unit?

Answer 2

2.23795229 × 1022 m2

Answer 3

No. an AU is a distance. It is the mean distance of the earth from the sun. It is approximately
1 AU = 150 million kms

Now, knowing that how much is 1.5 billion kms?

Answer 4

@JamesJ 0.1 AU?

Answer 5

Ok if
1 AU = 150 million kms
then
0.1 AU = 15 million kms

Does that sound right to you?

Also, could it possibly be the case that Saturn is closer to the sun than the earth?!

Answer 6

@JamesJ ohh okay so it would be 100AU then?

Answer 7

1 AU = 150 million kms.

How much is 100 AU?

Answer 8

@JamesJ 15000000?

Answer 9

1 AU = 150 million = 150,000,000
10 AU = 1,500,000,000
100 AU = 15,000,000,000

So what's the right answer?

Answer 10

@JamesJ 100 AU

Answer 11

Wait no. The question is this: Saturn is at a distance approximately of 1.5 billion kms from the Sun.

How many AU is that?

Answer 12

what is kms?

Answer 13

@JamesJ what is kms?

Answer 14

kilometers!

1 km = 1000 meters

Answer 15

10 AU?

Answer 16

The earth is about
150,000,000 kilometers from the sun, or
150,000,000 km

this is called 1 AU, because it's convenient.

Yes, Saturn is a distance of 10 AU from the sun.

Hence how many more times is Saturn distant from the sun than the earth?

Answer 17

15?

Answer 18

The Earth is a distance 1 AU from the Sun
Saturn is a distance of 10 AU from the Sun

Hence Saturn is 10 times further away from the Sun than the Earth.

Answer 19

Make sense?

Answer 20

This works in any units of distance of course:
Earth-Sun: 150,000,000 kms
Saturn-Sun: 1,500,000,000 kms ... which is 10 times more

Answer 21

@JamesJ ohhh okay i see now
