The distances between planets and the sun are much smaller and are typically measured in Astronomical Units (AU).
Here's a table showing the average distances of the planets from the sun in AU:
| Planet | Average Distance from Sun (AU) |
|-------------|---------------------------------|
| Mercury | 0.39 |
| Venus | 0.72 |
| Earth | 1.00 |
| Mars | 1.52 |
| Jupiter | 5.20 |
| Saturn | 9.58 |
| Uranus | 19.22 |
| Neptune | 30.06 |
To give you an idea of how small these distances are compared to a light year:
* 1 AU is approximately equal to 150 million kilometers (93 million miles).
* 1 light year is approximately equal to 9.461 trillion kilometers (5.879 trillion miles).
So, even the furthest planet, Neptune, is only about 0.000003 light years from the sun!
