I don't no so i can't tell you but i can tell you to ask your science teacher or a scientist....
(the worst answer....EVER)
Aphelion: 0.466697 AUPerihelion: 0.307499 AUMean: 0.387098 AU
0.387 is the average distance from the Sun to Mercury in AU. Note: AU=astronomical unit
Mercury--0.387 astronomical units Venus--0.723 astronomical units Earth--1.0 astronomical units Mars--1.524 astronomical units Jupiter--5.203 astronomical units Saturn--9.529 astronomical units Uranus--19.19 astronomical units Neptune--30.06 astronomical units Pluto--39.53 astronomical units Please note that these are all mean distances, and the actual distance will vary as to the location of the specific planet in its specific orbit.
70 million km (44 million miles), or 0.466 astronomical units
The distance between neptune and the sun is 15.0935 astronomical units (AU).
1.49 AU
Light year or astronomical units
Mars' average distance from the sun is about 1.52 astronomical units (AU), which is approximately 227.9 million kilometers.
The average distance between Mercury and Venus is approximately 0.5 astronomical units (AU), where 1 AU is approximately 93 million miles. One light year is about 63,241 AU, so the distance between Mercury and Venus is about 0.0000079 light years.
Jupiter's average distance from the sun is about 5.2 astronomical units (AU).
23412846662834 Units
4,500,000,000 kilometers = 30.1 astronomical units.
