Investigating Solar System: The table shows the average distance from each planet in our solar system to the sun.
(a) Complete the table by expressing the distance from each planet to the Sun in scientific notation.
(b) Order the planets from closest to the sun to farthest from the sun.
Solution:
(a) We have to complete the table by expressing the distance from each planet to the Sun in scientific notation.
| Planet | Distance from Sun (km) |
Distance from Sun (km) |
| Earth | 149,600,000 | 1.496 × 10⁸ |
| Jupiter | 778,300,000 | 7.783 × 10⁸ |
| Mars | 227,900,000 | 2.279 × 10⁸ |
| Mercury | 57,900,000 | 5.79 × 10⁸ |
| Neptune | 4,497,000,000 | 4.497 × 10⁸ |
