The purpose of using astronomical units by Astronomers is mainly to make comparisons about the distance between all celestial bodies that they can detect and study. This include galaxies. The main astronomical unit is the Light year. The calculation of astronomical distance involves highly complex mathematical formulas.
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.
29.76 astronomical units is how far away Neptune is from the Sun. An astronomical unit is the average distance of the Earth from the Sun, set at 93 million miles. Venus is .72 astronomical units from the Sun. Taking 29.76 and subtracting .72 shows us that Neptune is 29.04 astronomical units from Venus. Approximatey. On average. And can greatly vary due to eccentricities in orbits.
29 astronomical units = 4,338,338,250 kilometers.
4 astronomical units = 371,822,485 miles
1.93 astronomical units is 288,723,890 kilometers.
38 astronomical units is about 5,684,719,086 kilometers.
0.82 astronomical units is 122,670,254 kilometers.
39.5 astronomical units equate to about 5,909,115,892 kilometers.
1 light year = 63,240 Astronomical Units
9.5 Astronomical Units = 1.421181 × 1014 centimeters
9.54 astronomical units = 1,427,163,686 kilometers
Mars' average distance from the sun is about 1.52 astronomical units (AU), which is approximately 227.9 million kilometers.
