*** DOES
'BODE'S LAW' WORK?**

**Johann Bode** was a **German
astronomer**. **Bode's Law** is an interesting study in

**mathematics**, as it can be used
to remember the distances between the **planets**

from the **Sun** in our **Solar
System**. Sometimes, **astronomers** use **Astronomical**

**Units (AU)**, where **one
AU** is the distance **between** the **Earth** and the **Sun**.

**Bode's Law** has three
stages:

1 Write down a **series of numbers**, **doubling**
each number (after the **3**)

**0, 3, 6, 12, 24, 48,
....................**

2 **Add 4** to each number in the series

3 **Divide** each of the resulting numbers by **10**

1 *Complete the table below*, to see if
Bode's Law is useful for calculating distances in

the Solar System.

* Look back at the previous

2 Is **Bode's Law** always
exactly correct for calculating distances to the **planets** in

the **Solar System**?

3 How often is **Bode's Law**
almost correct for calculating distances to the **planets**

in the **Solar System**?

4 Is **Bode's Law** more correct
for calculating distances to the **inner planets** or to

the **outer planets**
in the **Solar System**?

5 **Bode's Law** seems to show a
gap between the **inner planets **and the **outer**

**planets** in the **Solar
System**, where we would expect **another planet** to be.

Can you find out anything about the
'missing planet' predicted by Bode's Law?
