Question

Earth is 1 AU and Neptune is 30.05 AU from the Sun. Suppose you were building a scale model of the solar system. If you placed Earth 1 inch away from the Sun, about how far away from the Sun should Neptune be?

Answer 1

30 astronomical units

Answer 2

Step-by-step explanation:

How many AU is Neptune from the Sun?

30 astronomical units

From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 4 hours to travel from the Sun to Neptune.
