Question
The table shows the average distance from each planet in our solar system to the sun.
| Planet | Distance from Sun (km) |
Distance from Sun (km) Standard Notation |
| Earth | 149,600,000 | 1.496 × 108 |
| Jupiter | 778,300,000 | |
| Mars | 227,900,000 | |
| Mercury | 57,900,000 | |
| Neptune | 4,497,000,000 | |
| Pluto | 5,900,000,000 | |
| Saturn | 1,427,000,000 | |
| Uranus | 2,870,000,000 | |
| Venus | 108,200,000 |
- Complete the table by expressing the distance from each planet to the Sun in scientific notation.
- Order the planets from closest to the sun to farthest from the sun.
Solution
a. Scientific notation of distance from Sun to
Earth = 149600000
= 1496 × 105
= 1.496 × 108
Jupiter = 149600000
= 1496 × 105
= 1.496 × 108
Mars = 227900000
= 2279 × 105
= 2.279 × 108
Mercury = 57900000
= 579 × 105
= 5.79 × 107
Neptune = 4497000000
= 4497 × 106
= 4.497 × 109
Pluto = 5900000000
= 59 × 108
= 5.9 × 109
Saturn = 1427000000
= 1427 × 106
= 1.427 × 109
Uranus = 2870000000
= 287 × 107
= 2.87 × 109
Venus = 108200000
= 1082 × 105
1.082 × 108
b. Order of planet from closest to the Sun to farthest from the Sun is given by
Mercury < Venus < Earth < Mars < Jupiter < Saturn < Uranus < Neptune < Pluto
