1 AU is the distance between the earth and the sun.
29.98 Since Neptune is 4497000000km away from the sun and an astronomical unit is 150 million km, you would divide 4497000000 by 150000000 and that is 29.98
Mars is 1.5 astronomical units away from sun while Neptune is 30 astronomical units away.
Same as Jupiter, since Callisto is a moon of Jupiter.
Betelgeuse is 40,473,416.93376 AU' (Astronomical Units) from Earth.
On average 1.52, but plus or minus 0.14.
1 AU
Jupiter is the fifth planet from the Sun, located about 4.95 astronomical units (AU) away. This is 483,800,000 miles and 778,500,000 kilometers.
Eris is 97 astronomical units away from the sun. ( an astronomical unit is the average distance between Earth and the Sun)
156855
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.
You use math in astronomy to measure the amount of astronomical units(150,000,000 km). Such as, the Earth is 1.5 astronomical units away from the sun.
The distance between neptune and the sun is 15.0935 astronomical units (AU).
